Trait embedded_io::blocking::Read

pub trait Read: Io {
    fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>;

    fn read_exact(
        &mut self, 
        buf: &mut [u8]
    ) -> Result<(), ReadExactError<Self::Error>> { ... }
}

Blocking reader.

Semantics are the same as std::io::Read, check its documentation for details.

Required Methods

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

Provided Methods

fn read_exact(
    &mut self,
    buf: &mut [u8]
) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.
