Expand description

Queue configuration control plane.

Required Associated Types§

Source

type Error

Concrete transport configuration error.

Required Methods§

Source

fn configure(&mut self, size: QueueSize) -> Result<(), QueueError<Self::Error>>

Configure queue size while the queue is not ready.

This operation must not block. It may allocate storage bounded by size; implementations must report allocation failure through Error without changing the prior configuration.

Source

fn set_ready(&mut self, ready: bool) -> Result<(), QueueError<Self::Error>>

Enable or disable queue descriptor processing.

This operation must not block or allocate. Making the queue ready is a release boundary for the configured queue state.

Dyn Compatibility§

This trait is dyn compatible.

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