Trait Read 

pub trait Read {
    type Error: Error;

    // Required method
    fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>;

    // Provided method
    fn read_exact(&mut self, buf: &mut [u8]) -> Result<()> { ... }
}

Read bytes from a source.

Required Associated Types

type Error: Error

Error returned by the underlying source.

Required Methods

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

Read some bytes, returning zero at end of input.

Provided Methods

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

Fill buf, retrying interrupted operations.

Dyn Compatibility

This trait is dyn compatible.

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