}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: IdentThe identifier for the field.
pat: P<Pat>The pattern the field is destructured to.

This is true if this AstLike might support ‘custom’ (proc-macro) inner
attributes. Attributes like #![cfg] and #![cfg_attr] are not
considered ‘custom’ attributes Read more
