Struct rustc_ast::ast::FieldDef

pub struct FieldDef {
    pub attrs: AttrVec,
    pub id: NodeId,
    pub span: Span,
    pub vis: Visibility,
    pub ident: Option<Ident>,
    pub ty: P<Ty>,
    pub is_placeholder: bool,
}

Field definition in a struct, variant or union.

E.g., bar: usize as in struct Foo { bar: usize }.

Fields

attrs: AttrVec

id: NodeId

span: Span

vis: Visibility

ident: Option<Ident>

ty: P<Ty>

is_placeholder: bool

Trait Implementations

impl AstLike for FieldDef

const SUPPORTS_CUSTOM_INNER_ATTRS: bool

This is true if this AstLike 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 Vec<Attribute>))

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

impl Clone for FieldDef

fn clone(&self) -> FieldDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FieldDef

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

Formats the value using the given formatter.

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

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

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

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

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.
