Required Methods

async fn sequential_read(&self, start: u64, list: &[PhysRange]) -> Result<usize>

async fn sequential_write( &self, start: u64, list: &[PhysRange], ) -> Result<usize>

async fn len(&self) -> Result<usize>

Provided Methods

async fn phys_addrs( &self, _start: DevicePage, _phys_list: &mut Vec<PagedPhysMem, MAYHEAP_LEN>, ) -> Result<usize>

Append the needed paged phys mem for this device page, return the number of appended pages.

fn yield_now(&self)

fn run_async<R: 'static>(&self, f: impl Future<Output = R>) -> R

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
