Struct rustc_hir::PatField

source ·
pub struct PatField<'hir> {
    pub hir_id: HirId,
    pub ident: Ident,
    pub pat: &'hir Pat<'hir>,
    pub is_shorthand: bool,
    pub span: Span,
}
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
