pub struct Lifetime {
pub hir_id: HirId,
pub span: Span,
pub name: LifetimeName,
}
Fields
hir_id: HirId
span: Span
name: LifetimeName
Either “'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.
