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

Trait Implementations

impl Clone for PatField

fn clone(&self) -> PatField

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatField

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for PatField

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for PatField

fn encode(&self, __encoder: &mut __E)

impl HasAttrs for PatField

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = false

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

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, f: impl FnOnce(&mut AttrVec))

impl HasNodeId for PatField

fn node_id(&self) -> NodeId

fn node_id_mut(&mut self) -> &mut NodeId

impl HasTokens for PatField

fn tokens(&self) -> Option<&LazyAttrTokenStream>

fn tokens_mut(&mut self) -> Option<&mut Option<LazyAttrTokenStream>>

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.
