Struct TraitRef 

pub struct TraitRef {
    pub def_id: TraitDef,
    args: GenericArgs,
}

A complete reference to a trait, i.e., one where Self is known.

Fields

def_id: TraitDef

args: GenericArgs

The generic arguments for this definition. The first element must always be type, and it represents Self.

Implementations

impl TraitRef

pub fn new(def_id: TraitDef, self_ty: Ty, gen_args: &GenericArgs) -> TraitRef

pub fn try_new(def_id: TraitDef, args: GenericArgs) -> Result<TraitRef, ()>

pub fn args(&self) -> &GenericArgs

pub fn self_ty(&self) -> Ty

pub fn vtable_entries(&self) -> Vec<VtblEntry>

Retrieve all vtable entries.

pub fn vtable_entry(&self, idx: usize) -> Option<VtblEntry>

Returns the vtable entry at the given index.

Returns None if the index is out of bounds.

Trait Implementations

impl Clone for TraitRef

fn clone(&self) -> TraitRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraitRef

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

Formats the value using the given formatter.

impl PartialEq for TraitRef

fn eq(&self, other: &TraitRef) -> 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 TraitRef

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TraitRef

impl StructuralPartialEq for TraitRef

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.
