Trait DmaTxBuffer 

pub unsafe trait DmaTxBuffer {
    type View;
    type Final;

    // Required methods
    fn prepare(&mut self) -> Preparation;
    fn into_view(self) -> Self::View;
    fn from_view(view: Self::View) -> Self::Final;
}

DmaTxBuffer is a DMA descriptor + memory combo that can be used for transmitting data from a DMA channel to a peripheral’s FIFO.

Safety

The implementing type must keep all its descriptors and the buffers they point to valid while the buffer is being transferred.

Required Associated Types

type View

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

type Final

The type returned to the user when a transfer finishes.

Some buffers don’t need to be reconstructed.

Required Methods

fn prepare(&mut self) -> Preparation

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

Note: This operation is idempotent.

fn into_view(self) -> Self::View

This is called before the DMA starts using the buffer.

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

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

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.
