Struct CoroutineLayout

pub struct CoroutineLayout<'tcx> {
    pub field_tys: IndexVec<CoroutineSavedLocal, CoroutineSavedTy<'tcx>>,
    pub field_names: IndexVec<CoroutineSavedLocal, Option<Symbol>>,
    pub variant_fields: IndexVec<VariantIdx, IndexVec<FieldIdx, CoroutineSavedLocal>>,

}

Expand description

The layout of coroutine state.

Fields§

§field_tys: IndexVec<CoroutineSavedLocal, CoroutineSavedTy<'tcx>>

The type of every local stored inside the coroutine.

§field_names: IndexVec<CoroutineSavedLocal, Option<Symbol>>

The name for debuginfo.

§variant_fields: IndexVec<VariantIdx, IndexVec<FieldIdx, CoroutineSavedLocal>>

Which of the above fields are in each variant. Note that one field may be stored in multiple variants.

§variant_source_info: IndexVec<VariantIdx, SourceInfo>

The source that led to each variant being created (usually, a yield or await).

§storage_conflicts: BitMatrix<CoroutineSavedLocal, CoroutineSavedLocal>

Which saved locals are storage-live at the same time. Locals that do not have conflicts with each other are allowed to overlap in the computed layout.
