Struct Lifetime

pub struct Lifetime {
    pub hir_id: HirId,
    pub ident: Ident,
    pub res: LifetimeName,
}

Fields

hir_id: HirId

ident: Ident

Either “'a”, referring to a named lifetime definition, '_ referring to an anonymous lifetime (either explicitly '_ or &type), or “``” (i.e., kw::Empty) when appearing in path.

See Lifetime::suggestion_position for practical use.

res: LifetimeName

Semantics of this lifetime.
