Implementations§
source§impl<'ast> LifetimeCollectVisitor<'ast>
impl<'ast> LifetimeCollectVisitor<'ast>
fn new(resolver: &'ast ResolverAstLowering) -> Self
fn record_lifetime_use(&mut self, lifetime: Lifetime)
sourcefn record_elided_anchor(&mut self, node_id: NodeId, span: Span)
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.
