Expand description
The nested types for a generator. This always appears inside a GeneratorDatum
Fields
resume_type: Ty<I>
The generator resume type - a value of this type is supplied by the caller when resuming the generator. Currently, this plays no rule in goal resolution.
yield_type: Ty<I>
The generator yield type - a value of this type is supplied by the generator during a yield. Currently, this plays no role in goal resolution.
return_type: Ty<I>
The generator return type - a value of this type is supplied by the generator when it returns. Currently, this plays no role in goal resolution
upvars: Vec<Ty<I>>
The upvars stored by the generator. These represent types captured from the generator’s environment, and are stored across all yields. These types (along with the witness types) are considered ‘constituent types’ for the purposes of determining auto trait implementations - that its, a generator impls an auto trait A iff all of its constituent types implement A.
Trait Implementations
type Result = GeneratorInputOutputDatum<I>
type Result = GeneratorInputOutputDatum<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
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
type Interner = I
type Interner = I
The interner associated with the type.
impl<I: PartialEq + Interner> PartialEq<GeneratorInputOutputDatum<I>> for GeneratorInputOutputDatum<I>
impl<I: PartialEq + Interner> PartialEq<GeneratorInputOutputDatum<I>> for GeneratorInputOutputDatum<I>
This method tests for self
and other
values to be equal, and is used
by ==
. Read more
This method tests for !=

using CastTo
.
Compare self to key

if they are equal.

pub fn shifted_in_from(
self,

Shifts a term valid at outer_binder
so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
for a detailed explanation. Read more
