Struct DriverDispatcherRef 

pub struct DriverDispatcherRef<'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> DriverDispatcherRef<'a>

pub unsafe fn from_raw( handle: NonNull<fdf_dispatcher>, ) -> DriverDispatcherRef<'a>

Creates a dispatcher ref from a raw handle.

Safety

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

pub fn from_async_dispatcher( dispatcher: AsyncDispatcherRef<'a>, ) -> DriverDispatcherRef<'a>

Creates a dispatcher ref from an AsyncDispatcherRef.

Panics

Note that this will cause an assert if the AsyncDispatcherRef was not created from a driver dispatcher in the first place.

pub unsafe fn as_raw(&mut self) -> *mut fdf_dispatcher

Gets the raw handle from this dispatcher ref.

Safety

Caller is responsible for ensuring that the dispatcher handle is used safely.

pub fn always_on_dispatcher(&self) -> DriverDispatcherRef<'a>

Returns a [DispatcherRef] for the always-on dispatcher associated with this dispatcher, preserving the lifetime parameter of the parent dispatcher.

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 allows_thread_migration(&self) -> bool

Whether this dispatcher is allowed to migrate threads, in which case it can’t be used for non-Send tasks.

pub fn is_current_dispatcher(&self) -> bool

Whether this is the dispatcher the current thread is running on

pub fn as_dispatcher_ref(&self) -> DriverDispatcherRef<'_>

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

Trait Implementations

fn as_async_dispatcher_ref(&self) -> AsyncDispatcherRef<'_>

Gets an AsyncDispatcherRef corresponding to this object.

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