Struct TaskExit 

pub struct TaskExit(/* private fields */);

Represents the completion of a task created using [Typed]Func::call_concurrent.

In general, a guest task may continue running after returning a value. Moreover, any given guest task may create its own subtasks before or after returning and may exit before some or all of those subtasks have finished running. In that case, the still-running subtasks will be “reparented” to the nearest surviving caller, which may be the original host call. The future returned by TaskExit::block will resolve once all transitive subtasks created directly or indirectly by the original call to Instance::call_concurrent have exited.

Implementations

impl TaskExit

pub async fn block(self, accessor: impl AsAccessor)

where <impl AsAccessor as AsAccessor>::Data: Send,

Returns a future which will resolve once all transitive subtasks created directly or indirectly by the original call to Instance::call_concurrent have exited.
