pub enum LiteralKind {
Verbatim,
Meta,
Superfluous,
Octal,
HexFixed(HexLiteralKind),
HexBrace(HexLiteralKind),
Special(SpecialLiteralKind),
}Expand description
The kind of a single literal expression.
The literal is written verbatim, e.g., a or ☃.
The literal is written as an escape because it is otherwise a special regex meta character, e.g., \* or \[.
The literal is written as an escape despite the fact that the escape is unnecessary, e.g., \% or \/.
The literal is written as an octal escape, e.g., \141.
The literal is written as a hex code with a fixed number of digits depending on the type of the escape, e.g., \x61 or \u0061 or\U00000061.
The literal is written as a hex code with a bracketed number of digits. The only restriction is that the bracketed hex code must refer to a valid Unicode scalar value.
The literal is written as a specially recognized escape, e.g., \for \n.

Tests for self and other values to be equal, and is used by ==.
Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
