Struct rustc_hir::PatField

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

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.
