Struct Utf32CodeUnits 

pub struct Utf32CodeUnits(pub u32);

A length or offset counted in 32-bit code units in UTF-32. This is the same as counting Rust chars, Unicode scalar values, or Unicode code points. This type is used to more reliable work with lengths or offsets in different encodings.

Tuple Fields

0: u32

Implementations

impl Utf32CodeUnits

impl Utf32CodeUnits

pub fn length_of(_: AssumeUnder4GB, string: &str) -> Self

Trait Implementations

impl Add for Utf32CodeUnits

type Output = Utf32CodeUnits

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl AddAssign for Utf32CodeUnits

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Clone for Utf32CodeUnits

fn clone(&self) -> Utf32CodeUnits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Utf32CodeUnits

Use compact formatting regardless of Formatter::alternate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Utf32CodeUnits

fn default() -> Utf32CodeUnits

Returns the “default value” for a type.

impl From<Utf32CodeUnits> for usize

fn from(value: Utf32CodeUnits) -> usize

Converts to this type from the input type.

impl From<u32> for Utf32CodeUnits

fn from(value: u32) -> Self

Converts to this type from the input type.

impl MallocSizeOf for Utf32CodeUnits

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Ord for Utf32CodeUnits

fn cmp(&self, other: &Utf32CodeUnits) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Utf32CodeUnits

fn eq(&self, other: &Utf32CodeUnits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Utf32CodeUnits

fn partial_cmp(&self, other: &Utf32CodeUnits) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub for Utf32CodeUnits

type Output = Utf32CodeUnits

The resulting type after applying the - operator.

fn sub(self, value: Self) -> Self

Performs the - operation.

impl SubAssign for Utf32CodeUnits

fn sub_assign(&mut self, other: Self)

Performs the -= operation.

impl Sum for Utf32CodeUnits

fn sum<I: Iterator<Item = Self>>(iter: I) -> Self

Takes an iterator and generates Self from the elements by “summing up” the items.

impl Copy for Utf32CodeUnits
