Trait IQueue 

pub unsafe trait IQueue: Send + 'static {
    // Required methods
    fn id(&self) -> usize;
    fn info(&self) -> QueueInfo;
    fn submit_request(
        &mut self,
        request: Request<'_>,
    ) -> Result<RequestId, BlkError>;
    fn poll_request(
        &mut self,
        request: RequestId,
    ) -> Result<RequestStatus, BlkError>;
}

A request queue for one block device hardware/software queue.

Safety

Implementers may access Request segments after submit_request returns and until the matching poll_request returns RequestStatus::Complete or an error. They must not access any segment before submit_request is called or after completion/error has been reported, and request IDs must not alias two concurrently pending requests in a way that extends this lifetime.

Required Methods

fn id(&self) -> usize

fn info(&self) -> QueueInfo

fn submit_request( &mut self, request: Request<'_>, ) -> Result<RequestId, BlkError>

fn poll_request( &mut self, request: RequestId, ) -> Result<RequestStatus, BlkError>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
