Trait SerialIo 

Source 
pub trait SerialIo: ErrorType {
    // Required methods
    fn try_read(&mut self, bytes: &mut [u8]) -> Result<usize, Self::Error>;
    fn try_write(&mut self, bytes: &[u8]) -> Result<usize, Self::Error>;
}

Required Methods§

Source

fn try_read(&mut self, bytes: &mut [u8]) -> Result<usize, Self::Error>

Read once without waiting, locking, allocating or retrying.

Source

fn try_write(&mut self, bytes: &[u8]) -> Result<usize, Self::Error>

Write once without waiting, locking, allocating or retrying. Ok(n) accepts exactly the first n <= bytes.len() bytes; Err accepts none.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
