Enum Direction 

pub enum Direction {
    Write,
    Read,
}

Whether an I2C transfer reads from or writes to the device.

The direction rides in the least-significant bit of the address byte: 0 for a write, 1 for a read.

Variants

Write

The controller writes to the device. R/W bit 0.

Read

The controller reads from the device. R/W bit 1.

Implementations

impl Direction

pub fn rw_bit(self) -> u8

Returns the R/W bit this direction places in the low bit of the address byte.

Returns

0 for Write, 1 for Read.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl Eq for Direction

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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.
