Struct chalk_solve::rust_ir::CoroutineWitnessDatum

pub struct CoroutineWitnessDatum<I: Interner> {
    pub inner_types: Binders<CoroutineWitnessExistential<I>>,
}

The coroutine witness data. Each CoroutineId has both a CoroutineDatum and a CoroutineWitnessDatum - these represent two distinct types in Rust. CoroutineWitnessDatum is logically ‘inside’ a coroutine - this only matters when we treat the witness type as a ’constituent type for the purposes of determining auto trait implementations.

Fields

inner_types: Binders<CoroutineWitnessExistential<I>>

This binder is identical to the input_output binder in CoroutineWitness - it binds the types and lifetimes that the coroutine is generic over. There is an additional binder inside CoroutineWitnessExistential, which is treated specially.

Trait Implementations

impl<I: Clone + Interner> Clone for CoroutineWitnessDatum<I>

fn clone(&self) -> CoroutineWitnessDatum<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<I: Debug + Interner> Debug for CoroutineWitnessDatum<I>

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

Formats the value using the given formatter.

impl<I: Interner> HasInterner for CoroutineWitnessDatum<I>

type Interner = I

The interner associated with the type.

impl<I: Hash + Interner> Hash for CoroutineWitnessDatum<I>

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<I: PartialEq + Interner> PartialEq for CoroutineWitnessDatum<I>

fn eq(&self, other: &CoroutineWitnessDatum<I>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<I: Interner> TypeFoldable<I> for CoroutineWitnessDatum<I>

fn try_fold_with<E>( self, folder: &mut dyn FallibleTypeFolder<I, Error = E>, outer_binder: DebruijnIndex, ) -> Result<Self, E>

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

fn fold_with( self, folder: &mut dyn TypeFolder<I, Error = Infallible>, outer_binder: DebruijnIndex, ) -> Self

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.
