Enum regex_syntax::hir::Literal
[−]
[src]
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.
