Struct CharRange 

pub struct CharRange {
    pub start: u32,
    pub end: u32,
}

A compact char range: all code points in [start, end] (inclusive).

Used to describe Unicode blocks or script ranges.

Fields

start: u32

First code point in the range.

end: u32

Last code point in the range (inclusive).

Implementations

impl CharRange

pub fn new(start: u32, end: u32) -> Self

Create a char range.

pub fn contains(&self, cp: u32) -> bool

Check whether a code point is within this range.

pub fn size(&self) -> u32

Number of code points in this range.

pub fn chars(&self) -> impl Iterator<Item = char>

Iterate over all valid chars in this range.

Trait Implementations

impl Clone for CharRange

fn clone(&self) -> CharRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharRange

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

Formats the value using the given formatter.

impl PartialEq for CharRange

fn eq(&self, other: &CharRange) -> 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.
