Struct rustc_ast_lowering::lifetime_collector::LifetimeCollectVisitor

struct LifetimeCollectVisitor<'ast> {
    resolver: &'ast ResolverAstLowering,
    current_binders: Vec<NodeId>,
    collected_lifetimes: Vec<Lifetime>,
}

Fields

resolver: &'ast ResolverAstLowering

current_binders: Vec<NodeId>

collected_lifetimes: Vec<Lifetime>

Implementations

impl<'ast> LifetimeCollectVisitor<'ast>

fn new(resolver: &'ast ResolverAstLowering) -> Self

fn record_lifetime_use(&mut self, lifetime: Lifetime)

fn record_elided_anchor(&mut self, node_id: NodeId, span: Span)

This collect lifetimes that are elided, for nodes like Foo<T> where there are no explicit lifetime nodes. Is equivalent to having “pseudo” nodes introduced for each of the node ids in the list start..end.

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.
