Struct chalk_solve::rust_ir::GeneratorWitnessDatum
source · [−]pub struct GeneratorWitnessDatum<I: Interner> {
pub inner_types: Binders<GeneratorWitnessExistential<I>>,
}Expand description
The generator witness data. Each GeneratorId has both a GeneratorDatum
and a GeneratorWitnessDatum - these represent two distinct types in Rust.
GeneratorWitnessDatum is logically ‘inside’ a generator - 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<GeneratorWitnessExistential<I>>This binder is identical to the input_output binder in GeneratorWitness -
it binds the types and lifetimes that the generator is generic over.
There is an additional binder inside GeneratorWitnessExistential, which
is treated specially.

sourceimpl<I: Interner> Fold<I> for GeneratorWitnessDatum<I>
impl<I: Interner> Fold<I> for GeneratorWitnessDatum<I>
type Result = GeneratorWitnessDatum<I>
type Result = GeneratorWitnessDatum<I>
The type of value that will be produced once folding is done.
Typically this is Self, unless Self contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T value where T: Fold, in which case
you get back a T, not a &T). Read more

fn fold_with<E>(
self,
folder: &mut dyn Folder<I, Error = E>,
outer_binder: DebruijnIndex
) -> Result<Self::Result, 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. Read more
