Struct ClassUnicodeRange

pub struct ClassUnicodeRange { /* private fields */ }

A single range of characters represented by Unicode scalar values.

The range is closed. That is, the start and end of the range are included in the range.

Implementations

impl ClassUnicodeRange

pub fn new(start: char, end: char) -> ClassUnicodeRange

Create a new Unicode scalar value range for a character class.

The returned range is always in a canonical form. That is, the range returned always satisfies the invariant that start <= end.

pub fn start(&self) -> char

Return the start of this range.

The start of a range is always less than or equal to the end of the range.

pub fn end(&self) -> char

Return the end of this range.

The end of a range is always greater than or equal to the start of the range.

pub fn len(&self) -> usize

Returns the number of codepoints in this range.

Trait Implementations

impl Clone for ClassUnicodeRange

fn clone(&self) -> ClassUnicodeRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClassUnicodeRange

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

Formats the value using the given formatter.

impl Default for ClassUnicodeRange

fn default() -> ClassUnicodeRange

Returns the “default value” for a type.

impl Ord for ClassUnicodeRange

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

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

fn partial_cmp(&self, other: &ClassUnicodeRange) -> 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
