The kind of a TransItemSource.

Variants

Global

TraitDecl

TraitImpl(TraitImplSource)

Fun

Type

InherentImpl

We don’t translate these as proper items, but we translate them a bit in names.

Module

We don’t translate these as proper items, but we use them to explore the crate.

ClosureMethod(ClosureKind)

The call_* method of the appropriate TraitImplSource::Closure impl.

ClosureAsFnCast

A cast of a state-less closure as a function pointer.

EmptyDropMethod

The drop method of a TraitImplSource::ImplicitDrop trait impl; that method does nothing.

DropInPlaceMethod(Option<TraitImplSource>)

The drop_in_place method of a Drop impl or decl. It contains the drop glue that calls Drop::drop for the type and then drops its fields. if the TraitImplSource is None this is the method declaration (and the DefId is that of the Drop trait), otherwise this is a method implementation (and the DefId is either that of a impl Drop for Foo impl, or that of an ADT in case of an implicit Drop impl).

VTable

The virtual table struct definition for a trait. The DefId is that of the trait.

VTableInstance(TraitImplSource)

The static vtable value for a specific impl.

VTableInstanceInitializer(TraitImplSource)

The initializer function of the VTableInstance.

VTableMethod

Shim function to store a method in a vtable; give a method with self: Ptr<Self> argument, this takes a Ptr<dyn Trait> and forwards to the method. The DefId refers to the method implementation.

Implementations

impl TransItemSourceKind

pub fn variant_index_arity(&self) -> (u32, usize)

Trait Implementations

impl Clone for TransItemSourceKind

fn clone(&self) -> TransItemSourceKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransItemSourceKind

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

Formats the value using the given formatter.

impl Hash for TransItemSourceKind

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 Ord for TransItemSourceKind

fn cmp(&self, other: &TransItemSourceKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransItemSourceKind

fn eq(&self, other: &TransItemSourceKind) -> 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 PartialOrd for TransItemSourceKind

fn partial_cmp(&self, other: &TransItemSourceKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
