Implementations§
source§impl<I: Interner> CoroutineArgs<I>
impl<I: Interner> CoroutineArgs<I>
sourcepub fn new(cx: I, parts: CoroutineArgsParts<I>) -> CoroutineArgs<I>
pub fn new(cx: I, parts: CoroutineArgsParts<I>) -> CoroutineArgs<I>
Construct CoroutineArgs
from CoroutineArgsParts
, containing Args
for the coroutine parent, alongside additional coroutine-specific components.
sourcefn split(self) -> CoroutineArgsParts<I>
fn split(self) -> CoroutineArgsParts<I>
Divides the coroutine args into their respective components.
The ordering assumed here must match that used by CoroutineArgs::new
above.
sourcepub fn parent_args(self) -> I::GenericArgsSlice
pub fn parent_args(self) -> I::GenericArgsSlice
Returns the generic parameters of the coroutine’s parent.
pub fn kind_ty(self) -> I::Ty
sourcepub fn witness(self) -> I::Ty
pub fn witness(self) -> I::Ty
This describes the types that can be contained in a coroutine. It will be a type variable initially and unified in the last stages of typeck of a body. It contains a tuple of all the types that could end up on a coroutine frame. The state transformation MIR pass may only produce layouts which mention types in this tuple. Upvars are not counted here.
sourcepub fn upvar_tys(self) -> I::Tys
pub fn upvar_tys(self) -> I::Tys
Returns an iterator over the list of types of captured paths by the coroutine. In case there was a type error in figuring out the types of the captured path, an empty iterator is returned.
sourcepub fn tupled_upvars_ty(self) -> I::Ty
pub fn tupled_upvars_ty(self) -> I::Ty
Returns the tuple type representing the upvars for this coroutine.
sourcepub fn resume_ty(self) -> I::Ty
pub fn resume_ty(self) -> I::Ty
Returns the type representing the resume type of the coroutine.

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
