Expand description
Enum variant.
Fields§
§attrs: AttrVec
Attributes of the variant.
id: NodeId
Id of the variant (not the constructor, see VariantData::ctor_id()
).
span: Span
Span
vis: Visibility
The visibility of the variant. Syntactically accepted but not semantically.
ident: Ident
Name of the variant.
data: VariantData
Fields and constructor id of the variant.
disr_expr: Option<AnonConst>
Explicit discriminant, e.g., Foo = 1
.
is_placeholder: bool
Is a macro placeholder

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. Read morefn attrs(&self) -> &[Attribute]

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.
