Enum rustc_resolve::late::lifetimes::Elide[−][src]

enum Elide {
    FreshLateAnon(u32, Cell<u32>),
    Exact(Region),
    Error(Vec<ElisionFailureInfo>),
    Forbid,
}

Variants

FreshLateAnon(u32, Cell<u32>)
Expand description

Use a fresh anonymous late-bound lifetime each time, by incrementing the counter to generate sequential indices. All anonymous lifetimes must start after named bound vars.

Exact(Region)
Expand description

Always use this one lifetime.

Error(Vec<ElisionFailureInfo>)
Expand description

Less or more than one lifetime were found, error on unspecified.

Forbid
Expand description

Forbid lifetime elision inside of a larger scope where it would be permitted. For example, in let position impl trait.
