pub const fn wrapping_div(self, rhs: u32) -> u32

Wrapping (modular) division. Computes self / rhs. Wrapped division on unsigned types is just normal division. There’s no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.

Wrapping Euclidean division. Computes self.div_euclid(rhs). Wrapped division on unsigned types is just normal division. There’s no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations. Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self.wrapping_div(rhs).

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100u32.wrapping_div_euclid(10), 10);

pub const fn wrapping_rem(self, rhs: u32) -> u32

assert_eq!(100u32.wrapping_rem_euclid(10), 0);

pub const fn wrapping_neg(self) -> u32

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0). For values smaller than the corresponding signed type’s maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to MAX + 1 - (val - MAX - 1) where MAX is the corresponding signed type’s maximum.

Examples

Basic usage:

assert_eq!(0_u32.wrapping_neg(), 0);
assert_eq!(u32::MAX.wrapping_neg(), 1);
assert_eq!(13_u32.wrapping_neg(), (!13) + 1);

pub const fn wrapping_shl(self, rhs: u32) -> u32

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left function, which may be what you want instead.

Examples

Basic usage:

assert_eq!(1u32.wrapping_shl(7), 128);
assert_eq!(1u32.wrapping_shl(128), 1);

pub const fn wrapping_shr(self, rhs: u32) -> u32

Panic-free bitwise shift-right; yields self >> mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right function, which may be what you want instead.

Examples

Basic usage:

assert_eq!(128u32.wrapping_shr(7), 1);

pub const fn overflowing_add(self, rhs: u32) -> (u32, bool)

Calculates self + rhs

Returns a tuple of the addition along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

assert_eq!(u32::MAX.overflowing_add(1), (0, true));

pub fn carrying_add(self, rhs: u32, carry: bool) -> (u32, bool)

🔬This is a nightly-only experimental API. (bigint_helper_methods)

Calculates self + rhs + carry and returns a tuple containing the sum and the output carry.

Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.

This can be thought of as a 32-bit “full adder”, in the electronics sense.

If the input carry is false, this method is equivalent to overflowing_add, and the output carry is equal to the overflow flag. Note that although carry and overflow flags are similar for unsigned integers, they are different for signed integers.

Examples

//    3  MAX    (a = 3 × 2^32 + 2^32 - 1)

🔬This is a nightly-only experimental API. (bigint_helper_methods)

Calculates self − rhs − borrow and returns a tuple containing the difference and the output borrow.

Performs “ternary subtraction” by subtracting both an integer operand and a borrow-in bit from self, and returns an output integer and a borrow-out bit. This allows chaining together multiple subtractions to create a wider subtraction, and can be useful for bignum subtraction.

Examples

#![feature(bigint_helper_methods)]

//    9    6    (a = 9 × 2^32 + 6)

Calculates the divisor when self is divided by rhs.

Returns a tuple of the divisor along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false.

Panics

Examples

Basic usage

pub const fn overflowing_div_euclid(self, rhs: u32) -> (u32, bool)

Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self.overflowing_div(rhs).

Panics

This function will panic if rhs is 0.

Examples

Basic usage

assert_eq!(5u32.overflowing_div_euclid(2), (2, false));

pub const fn overflowing_rem(self, rhs: u32) -> (u32, bool)

Calculates the remainder when self is divided by rhs.

Returns a tuple of the remainder after dividing along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false.

Panics

This function will panic if rhs is 0.

Examples

Basic usage

assert_eq!(5u32.overflowing_rem(2), (1, false));

pub const fn overflowing_rem_euclid(self, rhs: u32) -> (u32, bool)

Returns a tuple of the modulo after dividing along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false. Since, for the positive integers, all common definitions of division are equal, this operation is exactly equal to self.overflowing_rem(rhs).

Panics

This function will panic if rhs is 0.

Examples

Basic usage

assert_eq!(5u32.overflowing_rem_euclid(2), (1, false));

pub const fn overflowing_neg(self) -> (u32, bool)

Negates self in an overflowing fashion.

assert_eq!(2u32.overflowing_neg(), (-2i32 as u32, true));

pub const fn overflowing_shl(self, rhs: u32) -> (u32, bool)

Shifts self left by rhs bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

Examples

Basic usage

assert_eq!(0x1u32.overflowing_shl(4), (0x10, false));
assert_eq!(0x1u32.overflowing_shl(132), (0x10, true));

pub const fn to_be_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in big-endian (network) byte order.

Examples

let bytes = 0x12345678u32.to_be_bytes();

pub const fn to_le_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in little-endian byte order.

Examples

let bytes = 0x12345678u32.to_le_bytes();

pub const fn to_ne_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in native byte order.

As the target platform’s native endianness is used, portable code should use to_be_bytes or to_le_bytes, as appropriate, instead.

Examples

let bytes = 0x12345678u32.to_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        [0x12, 0x34, 0x56, 0x78]
    } else {
        [0x78, 0x56, 0x34, 0x12]
    }
);

pub const fn from_be_bytes(bytes: [u8; 4]) -> u32

Examples

let value = u32::from_be_bytes([0x12, 0x34, 0x56, 0x78]);
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_be_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_be_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_le_bytes(bytes: [u8; 4]) -> u32

Examples

let value = u32::from_le_bytes([0x78, 0x56, 0x34, 0x12]);
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_le_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_le_bytes(int_bytes.try_into().unwrap())
}

pub const fn from_ne_bytes(bytes: [u8; 4]) -> u32

Create a native endian integer value from its memory representation as a byte array in native endianness.

As the target platform’s native endianness is used, portable code likely wants to use from_be_bytes or from_le_bytes, as appropriate instead.

Examples

let value = u32::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78]
} else {
    [0x78, 0x56, 0x34, 0x12]
});
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_ne_u32(input: &mut &[u8]) -> u32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u32>());
    *input = rest;
    u32::from_ne_bytes(int_bytes.try_into().unwrap())
}

pub const fn min_value() -> u32

👎Deprecating in a future Rust version: replaced by the MIN associated constant on this type

New code should prefer to use u32::MIN instead.

Returns the smallest value that can be represented by this integer type.

pub const fn max_value() -> u32

👎Deprecating in a future Rust version: replaced by the MAX associated constant on this type

New code should prefer to use u32::MAX instead.

Returns the largest value that can be represented by this integer type.

pub fn widening_mul(self, rhs: u32) -> (u32, u32)

🔬This is a nightly-only experimental API. (bigint_helper_methods)

Calculates the complete product self * rhs without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

If you also need to add a carry to the wide result, then you want Self::carrying_mul instead.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why u32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5u32.widening_mul(2), (10, 0));
assert_eq!(1_000_000_000u32.widening_mul(10), (1410065408, 2));

pub fn carrying_mul(self, rhs: u32, carry: u32) -> (u32, u32)

🔬This is a nightly-only experimental API. (bigint_helper_methods)

Calculates the “full multiplication” self * rhs + carry without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the carry, then you can use Self::widening_mul instead.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why u32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
assert_eq!(5u32.carrying_mul(2, 10), (20, 0));
assert_eq!(1_000_000_000u32.carrying_mul(10, 0), (1410065408, 2));
assert_eq!(1_000_000_000u32.carrying_mul(10, 10), (1410065418, 2));
assert_eq!(u32::MAX.carrying_mul(u32::MAX, u32::MAX), (0, u32::MAX));

This is the core operation needed for scalar multiplication when implementing it for wider-than-native types.

#![feature(bigint_helper_methods)]
fn scalar_mul_eq(little_endian_digits: &mut Vec<u16>, multiplicand: u16) {
    let mut carry = 0;
    for d in little_endian_digits.iter_mut() {
        (*d, carry) = d.carrying_mul(multiplicand, carry);
    }
    if carry != 0 {
        little_endian_digits.push(carry);
    }
}

let mut v = vec![10, 20];
scalar_mul_eq(&mut v, 3);
assert_eq!(v, [30, 60]);

assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
let mut v = vec![0x4321, 0x8765];
scalar_mul_eq(&mut v, 0xFEED);
assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);

If carry is zero, this is similar to overflowing_mul, except that it gives the value of the overflow instead of just whether one happened:

#![feature(bigint_helper_methods)]
let r = u8::carrying_mul(7, 13, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
let r = u8::carrying_mul(13, 42, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));

The value of the first field in the returned tuple matches what you’d get by combining the wrapping_mul and wrapping_add methods:

#![feature(bigint_helper_methods)]
assert_eq!(
    789_u16.carrying_mul(456, 123).0,
    789_u16.wrapping_mul(456).wrapping_add(123),
);

pub fn midpoint(self, rhs: u32) -> u32

🔬This is a nightly-only experimental API. (num_midpoint)

Calculates the middle point of self and rhs.

midpoint(a, b) is (a + b) >> 1 as if it were performed in a sufficiently-large signed integral type. This implies that the result is always rounded towards negative infinity and that no overflow will ever occur.

Examples

#![feature(num_midpoint)]
assert_eq!(0u32.midpoint(4), 2);
assert_eq!(1u32.midpoint(4), 2);
