Implementations

impl AdtDef

pub fn kind(&self) -> AdtKind

pub fn ty(&self) -> Ty

Retrieve the type of this Adt.

pub fn ty_with_args(&self, args: &GenericArgs) -> Ty

Retrieve the type of this Adt by instantiating and normalizing it with the given arguments.

This will assume the type can be instantiated with these arguments.

pub fn is_box(&self) -> bool

pub fn is_simd(&self) -> bool

pub fn num_variants(&self) -> usize

The number of variants in this ADT.

pub fn variants(&self) -> Vec<VariantDef>

Retrieve the variants in this ADT.

pub fn variants_iter(&self) -> impl Iterator<Item = VariantDef> + '_

Iterate over the variants in this ADT.

pub fn variant(&self, idx: VariantIdx) -> Option<VariantDef>

Trait Implementations

impl Clone for AdtDef

fn clone(&self) -> AdtDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CrateDef for AdtDef

fn def_id(&self) -> DefId

Retrieve the unique identifier for the current definition.

fn name(&self) -> Symbol

Return the fully qualified name of the current definition.

fn trimmed_name(&self) -> Symbol

Return a trimmed name of this definition.

fn krate(&self) -> Crate

Return information about the crate where this definition is declared.

fn span(&self) -> Span

Return the span of this definition.

fn attrs_by_path(&self, attr: &[Symbol]) -> Vec<Attribute>

Return attributes with the given attribute name.

fn all_attrs(&self) -> Vec<Attribute>

Return all attributes of this definition.

impl Debug for AdtDef

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

Formats the value using the given formatter.

impl Hash for AdtDef

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 AdtDef

fn eq(&self, other: &AdtDef) -> 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 Serialize for AdtDef

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 AdtDef

impl Eq for AdtDef

impl StructuralPartialEq for AdtDef

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.
