Struct shared_bus::proxy::BusProxy

pub struct BusProxy<'a, M: 'a + BusMutex<RefCell<T>>, T>(_, _);

A proxy type that can be used instead of an actual bus peripheral.

BusProxy implements all bus traits and can thus be used in place of the actual bus peripheral.

BusProxies are created by calling BusManager::acquire

Trait Implementations

impl<'a, M, I2C: Read> Read<u8> for BusProxy<'a, M, I2C>where
    M: 'a + BusMutex<RefCell<I2C>>,

type Error = <I2C as Read<u8>>::Error

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, M, SPI: Transfer<u8>> Transfer<u8> for BusProxy<'a, M, SPI>where
    M: 'a + BusMutex<RefCell<SPI>>,

type Error = <SPI as Transfer<u8>>::Error

Error type

fn transfer<'w>(&mut self, words: &'w mut [u8]) -> Result<&'w [u8], Self::Error>

Sends words to the slave. Returns the words received from the slave

impl<'a, M, I2C: Write> Write<u8> for BusProxy<'a, M, I2C>where
    M: 'a + BusMutex<RefCell<I2C>>,

type Error = <I2C as Write<u8>>::Error

Error type

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

Writes bytes to slave with address address

impl<'a, M, SPI: Write<u8>> Write<u8> for BusProxy<'a, M, SPI>where
    M: 'a + BusMutex<RefCell<SPI>>,

type Error = <SPI as Write<u8>>::Error

Error type

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

Sends words to the slave, ignoring all the incoming words

impl<'a, M, I2C: WriteRead> WriteRead<u8> for BusProxy<'a, M, I2C>where
    M: 'a + BusMutex<RefCell<I2C>>,

type Error = <I2C as WriteRead<u8>>::Error

Error type

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

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