Trait embedded_serial::MutNonBlockingRx

pub trait MutNonBlockingRx {
    type Error;
    fn getc_try(&mut self) -> Result<Option<u8>, Self::Error>;

    fn gets_try<I: ?Sized>(
        &mut self, 
        buffer: &mut I
    ) -> Result<usize, (usize, Self::Error)>
    where
        I: AsMut<[u8]>,
    { ... }
}

Implementors of this trait offer octet based serial data reception using a non-blocking API, and requiring a mutable reference to self.

Associated Types

type Error

The error type returned if getc fails.

Required Methods

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

Attempt to read a single octet from the port's receiver; if the buffer is empty return None.

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.

Provided Methods

fn gets_try<I: ?Sized>(
    &mut self,
    buffer: &mut I
) -> Result<usize, (usize, Self::Error)> where
    I: AsMut<[u8]>, 

Read a specified number of octets into the given buffer, or until the data runs out.

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

If the result is Ok(size) but size <= buffer.len(), you ran out of data.
