Enum Pace 

pub enum Pace {
    PreferSource,
    PreferSink,
}

Pacing for DMA transfers.

Generally, while memory-to-memory DMA transfers can operate at maximum possible throughput, transfers involving peripherals commonly have to wait for data to be available or for available space in write queues. This type defines whether the sink or the source shall pace the transfer for peripheral-to-peripheral transfers.

Variants

PreferSource

The DREQ signal from the source is used, if available. If not, the sink’s DREQ signal is used.

PreferSink

The DREQ signal from the sink is used, if available. If not, the source’s DREQ signal is used.

Trait Implementations

impl Clone for Pace

fn clone(&self) -> Pace

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Pace

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

Formats the value using the given formatter.

impl PartialEq for Pace

fn eq(&self, other: &Pace) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
