Enum regex_syntax::hir::Literal

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

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

impl Literal

pub fn is_unicode(&self) -> bool

Returns true if and only if this literal corresponds to a Unicode scalar value.

Trait Implementations

impl Clone for Literal

fn clone(&self) -> Literal

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Literal

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