Enum litrs::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
