Trait Implementations

impl Debug for MappedRingMem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl RingMem for MappedRingMem

fn control(&self) -> &[AtomicU32; 32]

Returns the control page.

fn read_at(&self, addr: usize, data: &mut [u8])

Reads from the data portion of the ring, wrapping (once) at the end of the ring. Precondition: addr + data.len() <= self.len() * 2.

fn write_at(&self, addr: usize, data: &[u8])

Writes to the data portion of the ring, wrapping (once) at the end of the ring. Precondition: addr + data.len() <= self.len() * 2.

fn len(&self) -> usize

Returns the length of the ring in bytes.

fn read_aligned(&self, addr: usize, data: &mut [u8])

Reads from the data portion of the ring, as in [RingMem::read_at]. addr and data.len() must be multiples of 8.

fn write_aligned(&self, addr: usize, data: &[u8])

Writes to the data portion of the ring, as in [RingMem::write_at]. addr and data.len() must be multiples of 8.
