Trait tetsy_scale_codec::Input

pub trait Input {
    fn remaining_len(&mut self) -> Result<usize, Error>;
    fn read(&mut self, into: &mut [u8]) -> Result<(), Error>;

    fn read_byte(&mut self) -> Result<u8, Error> { ... }
}

Trait that allows reading of data into a slice.

Required methods

fn remaining_len(&mut self) -> Result<usize, Error>

Return remaining length of input.

fn read(&mut self, into: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill the given buffer.

Note that this function is similar to std::io::Read::read_exact and not std::io::Read::read.
