pub struct Lifetime {
pub hir_id: HirId,
pub span: Span,
pub name: LifetimeName,
}Fields§
§hir_id: HirId§span: Span§name: LifetimeNameEither “'a”, referring to a named lifetime definition,
or “``” (i.e., kw::Empty), for elision placeholders.
HIR lowering inserts these placeholders in type paths that
refer to type definitions needing lifetime parameters,
&T and &mut T, and trait objects without ... + 'a.

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.
