Struct AsyncFnPollEnv

pub struct AsyncFnPollEnv<'tcx> {
    pub async_fn_parent: Option<Instance<'tcx>>,
    pub creation_loc: Location,
    pub generator_data: Place<'tcx>,
}

Context for a call to Future::poll, when called on a future created via an async fn or an async block.

Fields

async_fn_parent: Option<Instance<'tcx>>

If the generator came from an async fn, then this is that function. If it is from an async block, this is None.

creation_loc: Location

Where was the async fn called, or where was the async block created.

generator_data: Place<'tcx>

A place which carries the runtime value representing the generator in the caller.
