Struct rustc_middle::mir::query::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>>,
    pub variant_source_info: IndexVec<VariantIdx, SourceInfo>,
    pub storage_conflicts: BitMatrix<CoroutineSavedLocal, CoroutineSavedLocal>,
}

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.

Trait Implementations

impl<'tcx> Clone for CoroutineLayout<'tcx>

fn clone(&self) -> CoroutineLayout<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoroutineLayout<'_>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for CoroutineLayout<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for CoroutineLayout<'tcx>

fn encode(&self, __encoder: &mut __E)

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for CoroutineLayout<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl ParameterizedOverTcx for CoroutineLayout<'static>

type Value<'tcx> = CoroutineLayout<'tcx>

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for CoroutineLayout<'tcx>

fn try_fold_with<__F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, __folder: &mut __F ) -> Result<Self, __F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Self

where F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for CoroutineLayout<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V ) -> ControlFlow<__V::BreakTy>

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

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.
