pub struct PatField<'hir> {
pub hir_id: HirId,

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
