Struct CharClass 

pub struct CharClass {
    pub negated: bool,
    pub items: Vec<CharClassItem>,
}

Character class definition.

Fields

negated: bool

Whether this is a negated class [^...].

items: Vec<CharClassItem>

The ranges/characters in this class.

Implementations

impl CharClass

pub fn new(negated: bool, items: Vec<CharClassItem>) -> Self

Create a new character class.

pub fn any() -> Self

Create a character class matching any character except newlines (default .).

pub fn any_with_newlines() -> Self

Create a character class matching any character including newlines (dot_all .).

pub fn digit() -> Self

Create a digit class (\d).

pub fn word() -> Self

Create a word class (\w).

pub fn whitespace() -> Self

Create a whitespace class (\s).

pub fn matches(&self, ch: char) -> bool

Check if a character matches this class.

pub fn matches_unicode(&self, ch: char) -> bool

Check if a character matches this class with Unicode support.

Trait Implementations

impl Clone for CharClass

fn clone(&self) -> CharClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CharClass

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

Formats the value using the given formatter.

impl From<&CharClass> for HirClass

fn from(class: &CharClass) -> Self

Converts to this type from the input type.

impl PartialEq for CharClass

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