Enum embedded_hal::spi::Operation

pub enum Operation<'a, Word: 'static> {
    Read(&'a mut [Word]),
    Write(&'a [Word]),
    Transfer(&'a mut [Word], &'a [Word]),
    TransferInPlace(&'a mut [Word]),
    DelayNs(u32),
}

SPI transaction operation.

This allows composition of SPI operations into a single bus transaction.

Variants

Read(&'a mut [Word])

Read data into the provided buffer.

Equivalent to SpiBus::read.

Write(&'a [Word])

Write data from the provided buffer, discarding read data.

Equivalent to SpiBus::write.

Transfer(&'a mut [Word], &'a [Word])

Read data into the first buffer, while writing data from the second buffer.

Equivalent to SpiBus::transfer.

TransferInPlace(&'a mut [Word])

Write data out while reading data into the provided buffer.

Equivalent to SpiBus::transfer_in_place.

DelayNs(u32)

Delay for at least the specified number of nanoseconds.

Trait Implementations

impl<'a, Word: Debug + 'static> Debug for Operation<'a, Word>

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

Formats the value using the given formatter.

impl<'a, Word: PartialEq + 'static> PartialEq for Operation<'a, Word>

fn eq(&self, other: &Operation<'a, Word>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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