Enum rustc_expand::mbe::macro_check::NestedMacroState

enum NestedMacroState {
    Empty,
    MacroRules,
    MacroRulesNot,
    MacroRulesNotName,
    Macro,
    MacroName,
    MacroNameParen,
}

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.

Trait Implementations

impl Clone for NestedMacroState

fn clone(&self) -> NestedMacroState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn eq(&self, other: &NestedMacroState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
