Expand description

The kind of a single literal expression.

Variants§

§

Verbatim

The literal is written verbatim, e.g., a or .

§

Meta

The literal is written as an escape because it is otherwise a special regex meta character, e.g., \* or \[.

§

Superfluous

The literal is written as an escape despite the fact that the escape is unnecessary, e.g., \% or \/.

§

Octal

The literal is written as an octal escape, e.g., \141.

§

HexFixed(HexLiteralKind)

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 or \u0061 or \U00000061.

§

HexBrace(HexLiteralKind)

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.

§

Special(SpecialLiteralKind)

The literal is written as a specially recognized escape, e.g., \f or \n.
