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.
