Struct UartBackend 

pub struct UartBackend<T> { /* private fields */ }

Passive UART backend adapter.

This type does not require std or heap allocation. The caller provides time through now_ms arguments, usually from SysTick or an RTOS tick.

Implementations

impl<T> UartBackend<T>

where T: UartIo,

pub fn new(io: T) -> Self

Creates a backend adapter using default MSRT config.

pub fn with_config(io: T, config: EngineConfig) -> Self

Creates a backend adapter using config.

pub fn peer_state(&self) -> PeerState

Returns the endpoint peer state.

pub const fn io(&self) -> &T

Returns a shared reference to the owned UART IO object.

pub fn io_mut(&mut self) -> &mut T

Returns a mutable reference to the owned UART IO object.

pub fn into_inner(self) -> T

Consumes the adapter and returns the UART IO object.

pub fn disconnect(&mut self)

Drops the active backend session.

pub fn send(&mut self, message: &[u8]) -> UartResult<bool, T::Error>

Queues an application message.

pub fn receive_available(&mut self, now_ms: u64) -> UartResult<usize, T::Error>

Reads currently available UART bytes and feeds them into MSRT.

pub fn poll(&mut self, now_ms: u64) -> UartResult<UartBackendEvent, T::Error>

Polls one backend event and writes pending UART bytes.

pub fn tick(&mut self, now_ms: u64) -> UartResult<UartBackendEvent, T::Error>

Runs receive_available followed by poll.
