Struct rustc_hir_analysis::variance::terms::TermsContext

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>>,
}

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.

Implementations

impl<'a, 'tcx> TermsContext<'a, 'tcx>

fn add_inferreds_for_item(&mut self, def_id: LocalDefId)

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.
