Enum litrs::BoolLit

pub enum BoolLit {
    False,
    True,
}

A bool literal: true or false. Also see the reference.

Notice that, strictly speaking, from Rust point of view “boolean literals” are not actual literals but keywords.

Variants

False

True

Implementations

impl BoolLit

pub fn parse(s: &str) -> Result<Self, ParseError>

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

pub fn value(self) -> bool

Returns the actual Boolean value of this literal.

pub fn as_str(&self) -> &'static str

Returns the literal as string.

Trait Implementations

impl Clone for BoolLit

fn clone(&self) -> BoolLit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BoolLit

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

Formats the value using the given formatter.

impl Display for BoolLit

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

Formats the value using the given formatter.

impl From<BoolLit> for Ident

fn from(l: BoolLit) -> Self

Converts to this type from the input type.

impl From<BoolLit> for Ident

fn from(l: BoolLit) -> Self

Converts to this type from the input type.

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

fn from(src: BoolLit) -> Self

Converts to this type from the input type.

impl PartialEq for BoolLit

fn eq(&self, other: &BoolLit) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&TokenTree> for BoolLit

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: &TokenTree) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&TokenTree> for BoolLit

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: &TokenTree) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<TokenTree> for BoolLit

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: TokenTree) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<TokenTree> for BoolLit

type Error = InvalidToken

The type returned in the event of a conversion error.

fn try_from(tt: TokenTree) -> Result<Self, Self::Error>

Performs the conversion.
