Struct CharLit

pub struct CharLit<B: Buffer> {
    raw: B,
    start_suffix: usize,
    value: char,
}

A character literal, e.g. 'g' or '🦊'.

See the reference for more information.

Fields

raw: B

start_suffix: usize

Start index of the suffix or raw.len() if there is no suffix.

value: char

Implementations

impl<B: Buffer> CharLit<B>

pub fn parse(input: B) -> Result<Self, ParseError>

Parses the input as a character literal. Returns an error if the input is invalid or represents a different kind of literal.

pub fn value(&self) -> char

Returns the character value that this literal represents.

pub fn suffix(&self) -> &str

The optional suffix. Returns "" if the suffix is empty/does not exist.

pub fn raw_input(&self) -> &str

Returns the raw input that was passed to parse.

pub fn into_raw_input(self) -> B

Returns the raw input that was passed to parse, potentially owned.

impl CharLit<&str>

pub fn to_owned(&self) -> CharLit<String>

Makes a copy of the underlying buffer and returns the owned version of Self.

Trait Implementations

impl<B: Clone + Buffer> Clone for CharLit<B>

fn clone(&self) -> CharLit<B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<B: Debug + Buffer> Debug for CharLit<B>

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

Formats the value using the given formatter.

impl<B: Buffer> Display for CharLit<B>

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

Formats the value using the given formatter.

impl<B: Buffer> From<CharLit<B>> for Literal

fn from(l: CharLit<B>) -> Self

Converts to this type from the input type.

impl<B: Buffer> From<CharLit<B>> for Literal<B>

fn from(src: CharLit<B>) -> Self

Converts to this type from the input type.

impl<B: PartialEq + Buffer> PartialEq for CharLit<B>

fn eq(&self, other: &CharLit<B>) -> 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.
