Struct rustc_ast::ast::ExprField

pub struct ExprField {
    pub attrs: AttrVec,
    pub id: NodeId,
    pub span: Span,
    pub ident: Ident,
    pub expr: P<Expr>,
    pub is_shorthand: bool,
    pub is_placeholder: bool,
}

A single field in a struct expression, e.g. x: value and y in Foo { x: value, y }.

Fields

attrs: AttrVec

id: NodeId

span: Span

ident: Ident

expr: P<Expr>

is_shorthand: bool

is_placeholder: bool

Trait Implementations

impl Clone for ExprField

fn clone(&self) -> ExprField

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprField

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

Formats the value using the given formatter.

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

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

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

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

impl HasAttrs for ExprField

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 ExprField

fn node_id(&self) -> NodeId

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

impl HasTokens for ExprField

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.
