Struct FieldDef

pub struct FieldDef {
    pub attrs: AttrVec,
    pub id: NodeId,
    pub span: Span,
    pub vis: Visibility,
    pub safety: Safety,
    pub ident: Option<Ident>,
    pub ty: P<Ty>,
    pub default: Option<AnonConst>,
    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

safety: Safety

ident: Option<Ident>

ty: P<Ty>

default: Option<AnonConst>

is_placeholder: bool

Trait Implementations

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: SpanDecoder> Decodable<__D> for FieldDef

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

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

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

impl HasAttrs for FieldDef

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 FieldDef

fn node_id(&self) -> NodeId

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

impl HasTokens for FieldDef

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.
