Enum 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

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.

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

impl<'a, Word: 'static> StructuralPartialEq for Operation<'a, Word>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
