Enum rustc_middle::middle::resolve_lifetime::LifetimeScopeForPath

pub enum LifetimeScopeForPath {
    NonElided(Vec<String>),
    Elided,
}

This is used in diagnostics to improve suggestions for missing generic arguments. It gives information on the type of lifetimes that are in scope for a particular PathSegment, so that we can e.g. suggest elided-lifetimes-in-paths of the form <’, ’> e.g.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
