pub struct EmptyBuf;

An empty buffer that can be used when you don’t need to transfer any data.

Trait Implementations

impl DmaRxBuffer for EmptyBuf

type View = EmptyBuf

A type providing operations that are safe to perform on the buffer whilst the DMA is actively using it.

fn prepare(&mut self) -> Preparation

Prepares the buffer for an imminent transfer and returns information required to use this buffer.

fn into_view(self) -> EmptyBuf

This is called before the DMA starts using the buffer.

fn from_view(view: Self::View) -> Self

This is called after the DMA is done using the buffer.

fn length(&self) -> usize

Returns the maximum number of bytes that can be received by this buffer.
