source · pub struct CanRx<'d> { /* private fields */ }Expand description
CAN driver, receive half.
Implementations§
source§impl<'d> CanRx<'d>
impl<'d> CanRx<'d>
sourcepub async fn read(&mut self) -> Result<Envelope, BusError>
pub async fn read(&mut self) -> Result<Envelope, BusError>
Read a CAN frame.
If no CAN frame is in the RX buffer, this will wait until there is one.
Returns a tuple of the time the message was received and the message frame
sourcepub fn try_read(&mut self) -> Result<Envelope, TryReadError>
pub fn try_read(&mut self) -> Result<Envelope, TryReadError>
Attempts to read a CAN frame without blocking.
Returns [Err(TryReadError::Empty)] if there are no frames in the rx queue.
sourcepub async fn wait_not_empty(&mut self)
pub async fn wait_not_empty(&mut self)
Waits while receive queue is empty.
sourcepub fn buffered<const RX_BUF_SIZE: usize>(
self,
rxb: &'static mut RxBuf<RX_BUF_SIZE>,
) -> BufferedCanRx<'d, RX_BUF_SIZE>
pub fn buffered<const RX_BUF_SIZE: usize>( self, rxb: &'static mut RxBuf<RX_BUF_SIZE>, ) -> BufferedCanRx<'d, RX_BUF_SIZE>
Return a buffered instance of driver. User must supply Buffers
