pub const fn wrapping_neg(self) -> u1281.2.0[src]

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:

#[must_use = "this returns the result of the operation, without modifying the original"]
pub const fn wrapping_shl(self, rhs: u32) -> u128
1.2.0[src]

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

#[must_use = "this returns the result of the operation, without modifying the original"]
pub fn div_euclid(self, rhs: u128) -> u128
[src]

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

Performs Euclidean division.

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

Examples

Basic usage:

#![feature(euclidean_division)]
assert_eq!(7u128.div_euclid(4), 1); // or any other integer typeRun

#[must_use = "this returns the result of the operation, without modifying the original"]
pub fn rem_euclid(self, rhs: u128) -> u128
[src]

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

Calculates the least remainder of self (mod rhs).

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

Examples

Basic usage:

#![feature(euclidean_division)]
assert_eq!(7u128.rem_euclid(4), 3); // or any other integer typeRun

pub fn is_power_of_two(self) -> bool1.0.0[src]

Returns true if and only if self == 2^k for some k.

Examples

Basic usage:

assert!(16u128.is_power_of_two());
assert!(!10u128.is_power_of_two());Run

pub fn next_power_of_two(self) -> u1281.0.0[src]

Returns the smallest power of two greater than or equal to self.

When return value overflows (i.e., self > (1 << (N-1)) for type uN), it panics in debug mode and return value is wrapped to 0 in release mode (the only situation in which method can return 0).

Examples

Basic usage:

assert_eq!(2u128.next_power_of_two(), 2);
assert_eq!(3u128.next_power_of_two(), 4);Run

pub fn checked_next_power_of_two(self) -> Option<u128>1.0.0[src]

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type's maximum value, None is returned, otherwise the power of two is wrapped in Some.

Examples

Basic usage:

assert_eq!(2u128.checked_next_power_of_two(), Some(2));
assert_eq!(3u128.checked_next_power_of_two(), Some(4));
assert_eq!(u128::max_value().checked_next_power_of_two(), None);Run

pub fn wrapping_next_power_of_two(self) -> u128[src]

🔬 This is a nightly-only experimental API. (wrapping_next_power_of_two #32463)

needs decision on wrapping behaviour

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type's maximum value, the return value is wrapped to 0.

Examples

Basic usage:

#![feature(wrapping_next_power_of_two)]

assert_eq!(2u128.wrapping_next_power_of_two(), 2);
assert_eq!(3u128.wrapping_next_power_of_two(), 4);
assert_eq!(u128::max_value().wrapping_next_power_of_two(), 0);Run

pub fn to_ne_bytes(self) -> [u8; 16]1.32.0[src]

assert_eq!(value, 0x12345678901234567890123456789012);Run

}Run

pub fn from_ne_bytes(bytes: [u8; 16]) -> u1281.32.0[src]

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