}
Expand description
A single field in a struct pattern.
Patterns like the fields of Foo { x, ref y, ref mut z }
are treated the same as x: x, y: ref y, z: ref mut z
,
except is_shorthand
is true.
Fields§
§hir_id: HirId
§ident: Ident
The identifier for the field.
pat: &'hir Pat<'hir>
The pattern the field is destructured to.
is_shorthand: bool
§span: Span

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.
