Struct Queue

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

A kernel work queue.

Wraps the kernel’s C struct workqueue_struct.

It allows work items to be queued to run on thread pools managed by the kernel. Several are always available, for example, system, system_highpri, system_long, etc.

Implementations

impl Queue

pub unsafe fn from_raw<'a>(ptr: *const workqueue_struct) -> &'a Queue

Use the provided struct workqueue_struct with Rust.

Safety

The caller must ensure that the provided raw pointer is not dangling, that it points at a valid workqueue, and that it remains valid until the end of 'a.

pub fn enqueue<W, const ID: u64>(&self, w: W) -> W::EnqueueOutput

where W: RawWorkItem<ID> + Send + 'static,

Enqueues a work item.

This may fail if the work item is already enqueued in a workqueue.

The work item will be submitted using WORK_CPU_UNBOUND.

pub fn try_spawn<T: 'static + Send + FnOnce()>( &self, flags: Flags, func: T, ) -> Result<(), AllocError>

Tries to spawn the given function or closure as a work item.

This method can fail because it allocates memory to store the work item.
