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 when is_shorthand
is true.
Fields§
§ident: Ident
The identifier for the field.
pat: P<Pat>
The pattern the field is destructured to.
is_shorthand: bool
§attrs: AttrVec
§id: NodeId
§span: Span
§is_placeholder: bool

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
