Enum litrs::Literal[−][src]

pub enum Literal<B: Buffer> {
    Bool(BoolLit),
    Integer(IntegerLit<B>),

    Char(CharLit<B>),
    String(StringLit<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<B>)
Float(FloatLit<B>)
Char(CharLit<B>)
String(StringLit<B>)
Byte(ByteLit<B>)
ByteString(ByteStringLit<B>)

Implementations

impl<B: Buffer> Literal<B>[src]

Parses the given input as a Rust literal.

impl Literal<&str>[src]
