Expand description

Represents the processed prefix of a nested macro.

Variants

Empty

Nothing that matches a nested macro definition was processed yet.

MacroRules

The token macro_rules was processed.

MacroRulesNot

The tokens macro_rules! were processed.

MacroRulesNotName

The tokens macro_rules! followed by a name were processed. The name may be either directly an identifier or a meta-variable (that hopefully would be instantiated by an identifier).

Macro

The keyword macro was processed.

MacroName

The keyword macro followed by a name was processed.

MacroNameParen

The keyword macro followed by a name and a token delimited by parentheses was processed.
