Struct VariantDef

pub struct VariantDef {
    pub idx: VariantIdx,
    pub adt_def: AdtDef,
}

Definition of a variant, which can be either a struct / union field or an enum variant.

Fields

idx: VariantIdx

The variant index.

Warning

Do not access this field directly!

adt_def: AdtDef

The data type where this variant comes from. For now, we use this to retrieve information about the variant itself so we don’t need to cache more information.

Warning

Do not access this field directly!

Implementations

impl VariantDef

pub fn name(&self) -> Symbol

pub fn fields(&self) -> Vec<FieldDef>

Retrieve all the fields in this variant.

Trait Implementations

impl Clone for VariantDef

fn clone(&self) -> VariantDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VariantDef

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

Formats the value using the given formatter.

impl Hash for VariantDef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VariantDef

fn eq(&self, other: &VariantDef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RustcInternal for VariantDef

type T<'tcx> = &'tcx VariantDef

fn internal<'tcx>( &self, tables: &mut Tables<'_>, tcx: TyCtxt<'tcx>, ) -> Self::T<'tcx>

impl Serialize for VariantDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for VariantDef

impl Eq for VariantDef

impl StructuralPartialEq for VariantDef

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.
