pub enum Literal {
    Unicode(char),
    Byte(u8),
}
Expand description

The high-level intermediate representation of a literal.

A literal corresponds to a single character, where a character is either defined by a Unicode scalar value or an arbitrary byte. Unicode characters are preferred whenever possible. In particular, a Byte variant is only ever produced when it could match invalid UTF-8.

Variants§

§

Unicode(char)

A single character represented by a Unicode scalar value.

§

Byte(u8)

A single character represented by an arbitrary byte.

Implementations§

source§

impl Literal
