Struct rustc_hir::hir::Lifetime

source ·
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.
