Struct embedded_hal_mock::i2c::Mock

pub struct Mock<'a> { /* fields omitted */ }

Mock I²C implementation

The main idea behind this is that you set the data that will be read back by a read call in advance. Then the driver can read from the mock device, and will get exactly the data you prepared.

See the usage section in the module level docs for an example.

Methods

impl<'a> Mock<'a>

pub fn new() -> Self

pub fn set_read_data(&mut self, data: &'a [u8])

Set data that will be read by read().

pub fn get_write_data(&self) -> &[u8]

Return the data that was written by the last write command.

pub fn get_last_address(&self) -> Option<u8>

Return the address that was used by the last read or write command.

Trait Implementations

impl<'a> Read for Mock<'a>

type Error = MockError

Error type

fn read(&mut self, address: u8, buffer: &mut [u8]) -> Result<(), Self::Error>

Reads enough bytes from slave with address to fill buffer

impl<'a> Write for Mock<'a>

type Error = MockError

Error type

fn write(&mut self, address: u8, bytes: &[u8]) -> Result<(), Self::Error>

Sends bytes to slave with address addr

impl<'a> WriteRead for Mock<'a>

type Error = MockError

Error type

fn write_read(     &mut self,     address: u8,     bytes: &[u8],     buffer: &mut [u8] ) -> Result<(), Self::Error>

Sends bytes to slave with address addr and then reads enough bytes to fill buffer in a single transaction
