Struct UartBusHandle 

pub struct UartBusHandle { /* private fields */ }

Owned handle to an async UART bus.

Dropping this handle does not return its startup resources, so keep it alive for as long as you need UART access.

Implementations

impl UartBusHandle

pub fn new(inner: Box<dyn DynUartBus>, version: UartBusVersion) -> Self

Wraps a boxed backend and records its UartBusVersion.

pub fn version(&self) -> UartBusVersion

Returns the backend variant.

Trait Implementations

impl ErrorType for UartBusHandle

type Error = UartError

Error type of all the IO operations on this type.

impl Read for UartBusHandle

async fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

async fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl Write for UartBusHandle

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

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

async fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.
