Enum litrs::Literal[−][src]

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>),
}

Expand description

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)

Float(FloatLit)

Char(CharLit)

String(StringLit)

Byte(ByteLit)

ByteString(ByteStringLit)

impl Literal<&str>[src]

pub fn into_owned(self) -> OwnedLiteral[src]
