Struct ImplTraitLoweringState

Source

struct ImplTraitLoweringState {
    mode: ImplTraitLoweringMode,
    opaque_type_data: Arena<ImplTrait>,
}

Fields§

§mode: ImplTraitLoweringMode

When turning impl Trait into opaque types, we have to collect the bounds at the same time to get the IDs correct (without becoming too complicated).
