Struct rustc_hir_analysis::variance::terms::TermsContext
source · pub struct TermsContext<'a, 'tcx> {
pub tcx: TyCtxt<'tcx>,
pub arena: &'a DroplessArena,
pub lang_items: Vec<(LocalDefId, Vec<Variance>)>,
pub inferred_starts: LocalDefIdMap<InferredIndex>,
pub inferred_terms: Vec<&'a VarianceTerm<'a>>,
}Expand description
The first pass over the crate simply builds up the set of inferreds.
Fields§
§tcx: TyCtxt<'tcx>§arena: &'a DroplessArena§lang_items: Vec<(LocalDefId, Vec<Variance>)>For marker types, UnsafeCell, and other lang items where
variance is hardcoded, records the item-id and the hardcoded
variance.
inferred_starts: LocalDefIdMap<InferredIndex>Maps from the node id of an item to the first inferred index used for its type & region parameters.
inferred_terms: Vec<&'a VarianceTerm<'a>>Maps from an InferredIndex to the term for that variable.

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.
