Trait embedded_serial::BlockingRxWithTimeout

pub trait BlockingRxWithTimeout {
    type Timeout;
    type Error;
    fn getc_to(&mut self,
               timeout: &Self::Timeout)
               -> Result<Option<u8>, Self::Error>;
}

Implementors of this trait offer octet based serial data reception using a blocking API with an upper bound on blocking time, and requiring a mutable reference to self.

Associated Types

type Timeout

The type used to specify the timeout.

type Error

The error type returned if getc fails.

Required Methods

fn getc_to(&mut self,
           timeout: &Self::Timeout)
           -> Result<Option<u8>, Self::Error>

Read a single octet from the port's receiver, blocking until the character can be read from the buffer.

In some implementations, this can result in an Error. If not, use type Error = !.

If it times out, Ok(None) is returned. If it receives data, Ok(Some(data)) is returned. If it fails, Err(...) is returned.
