Struct rustc_expand::mbe::macro_check::MacroState[−][src]

struct MacroState<'a> {
    binders: &'a FxHashMap<MacroRulesNormalizedIdent, BinderInfo>,
    ops: SmallVec<[KleeneToken; 1]>,
}
Expand description

The state at which we entered a macro definition in the RHS of another macro definition.

Fields

binders: &'a FxHashMap<MacroRulesNormalizedIdent, BinderInfo>
Expand description

The binders of the branch where we entered the macro definition.

ops: SmallVec<[KleeneToken; 1]>
Expand description

The stack of Kleene operators (outermost first) where we entered the macro definition.
