Struct rustc_expand::mbe::macro_check::MacroState

source · 
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>

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

§ops: SmallVec<[KleeneToken; 1]>

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

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.
