Struct Utf8CodeUnits 

pub struct Utf8CodeUnits(pub usize);

A length or offset counted in 8-bit code units (bytes) in an UTF-8 string. This type is used to more reliable work with lengths or offsets in different encodings.

Tuple Fields

0: usize

Implementations

impl Utf8CodeUnits

pub fn zero() -> Self

pub fn one() -> Self

pub fn saturating_sub(self, value: Self) -> Self

Trait Implementations

impl Add for Utf8CodeUnits

type Output = Utf8CodeUnits

The resulting type after applying the + operator.

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

Performs the + operation.

impl AddAssign for Utf8CodeUnits

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Clone for Utf8CodeUnits

fn clone(&self) -> Utf8CodeUnits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Utf8CodeUnits

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

Formats the value using the given formatter.

impl Default for Utf8CodeUnits

fn default() -> Utf8CodeUnits

Returns the “default value” for a type.

impl From<isize> for Utf8CodeUnits

fn from(value: isize) -> Self

Converts to this type from the input type.

impl From<u32> for Utf8CodeUnits

fn from(value: u32) -> Self

Converts to this type from the input type.

impl MallocSizeOf for Utf8CodeUnits

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 Utf8CodeUnits

fn cmp(&self, other: &Utf8CodeUnits) -> 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 Utf8CodeUnits

fn eq(&self, other: &Utf8CodeUnits) -> 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 Utf8CodeUnits

fn partial_cmp(&self, other: &Utf8CodeUnits) -> 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 Utf8CodeUnits

type Output = Utf8CodeUnits

The resulting type after applying the - operator.

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

Performs the - operation.

impl SubAssign for Utf8CodeUnits

fn sub_assign(&mut self, other: Self)

Performs the -= operation.

impl Sum for Utf8CodeUnits

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 Utf8CodeUnits

impl Eq for Utf8CodeUnits

impl StructuralPartialEq for Utf8CodeUnits
