Enum Literal

pub enum Literal<B: Buffer> {
    Bool(BoolLit),
    Integer(IntegerLit<B>),
    Float(FloatLit<B>),
    Char(CharLit<B>),
    String(StringLit<B>),
    Byte(ByteLit<B>),
    ByteString(ByteStringLit<B>),
}

A literal. This is the main type of this library.

This type is generic over the underlying buffer B, which can be &str or String. There are two useful type aliases: OwnedLiteral and SharedLiteral.

To create this type, you have to either call Literal::parse with an input string or use the From<_> impls of this type. The impls are only available of the corresponding crate features are enabled (they are enabled by default).

Variants

Bool(BoolLit)

Integer(IntegerLit<B>)

Float(FloatLit<B>)

Char(CharLit<B>)

String(StringLit<B>)

Byte(ByteLit<B>)

ByteString(ByteStringLit<B>)

Implementations

impl<B: Buffer> Literal<B>

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

Parses the given input as a Rust literal.

impl Literal<&str>

pub fn into_owned(self) -> OwnedLiteral

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

Trait Implementations

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

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

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

Formats the value using the given formatter.

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

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

Formats the value using the given formatter.

impl From<&Literal> for Literal<String>

fn from(src: &Literal) -> 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<B: Buffer> From<ByteLit<B>> for Literal<B>

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

Converts to this type from the input type.

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

fn from(src: ByteStringLit<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: Buffer> From<FloatLit<B>> for Literal<B>

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<Literal> for Literal<String>

fn from(src: Literal) -> Self

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

fn eq(&self, other: &Literal<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.

impl TryFrom<&TokenTree> for Literal<String>

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 Literal<String>

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.
