Struct rustc_ast::ast::PatField

pub struct PatField {
    pub ident: Ident,
    pub pat: P<Pat>,
    pub is_shorthand: bool,
    pub attrs: AttrVec,
    pub id: NodeId,
    pub span: Span,
    pub is_placeholder: bool,
}

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
