Struct DispatcherRef

pub struct DispatcherRef<'a>(/* private fields */);

An unowned reference to a driver runtime dispatcher such as is produced by calling Dispatcher::release. When this object goes out of scope it won’t shut down the dispatcher, leaving that up to the driver runtime or another owner.

Implementations

impl<'a> DispatcherRef<'a>

pub unsafe fn from_raw(handle: NonNull<fdf_dispatcher_t>) -> Self

Creates a dispatcher ref from a raw handle.

Safety

Caller is responsible for ensuring that the given handle is valid for the lifetime 'a.

Methods from Deref<Target = Dispatcher>

pub fn is_unsynchronized(&self) -> bool

Whether this dispatcher’s tasks and futures can run on multiple threads at the same time.

pub fn allows_thread_blocking(&self) -> bool

Whether this dispatcher is allowed to call blocking functions or not

pub fn post_task_sync<'a>(&self, p: impl TaskCallback<'a>) -> Result<(), Status>

pub fn spawn_task<'a>( &'a self, future: impl Future<Output = ()> + 'a + Send, ) -> Result<(), Status>

pub fn as_ref(&self) -> DispatcherRef<'_>

Returns a DispatcherRef that references this dispatcher with a lifetime constrained by self.
