Struct rustc_ast_lowering::LifetimeCaptureContext

source · [−]
pub(crate) struct LifetimeCaptureContext {
    pub(crate) parent_def_id: LocalDefId,
    pub(crate) captures: FxHashMap<LocalDefId, (Span, NodeId, ParamName, LifetimeRes)>,
    pub(crate) binders_to_ignore: FxHashSet<NodeId>,
}
Expand description

When we lower a lifetime, it is inserted in captures, and the resolution is modified so to point to the lifetime parameter impl-trait will generate. When traversing for<...> binders, they are inserted in binders_to_ignore so we know not to rebind the introduced lifetimes.

Fields

parent_def_id: LocalDefId

parent def_id for new definitions

captures: FxHashMap<LocalDefId, (Span, NodeId, ParamName, LifetimeRes)>

Set of lifetimes to rebind.

binders_to_ignore: FxHashSet<NodeId>

Traversed binders. The ids in this set should not be rebound.

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.
