Fields§

§saved_locals: GeneratorSavedLocals

Which locals are live across any suspension point.

§live_locals_at_suspension_points: Vec<BitSet<GeneratorSavedLocal>>

The set of saved locals live at each suspension point.

§source_info_at_suspension_points: Vec<SourceInfo>

Parallel vec to the above with SourceInfo for each yield terminator.

§storage_conflicts: BitMatrix<GeneratorSavedLocal, GeneratorSavedLocal>

For every saved local, the set of other saved locals that are storage-live at the same time as this local. We cannot overlap locals in the layout which have conflicting storage.

§storage_liveness: IndexVec<BasicBlock, Option<BitSet<Local>>>

For every suspending block, the locals which are storage-live across that suspension point.

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.
