Trait Read

pub trait Read {
    // Required method
    fn read(&mut self, buf: &mut [u8]) -> Result<usize>;

    // Provided methods
    fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize> { ... }
    fn read_to_string(&mut self, buf: &mut String) -> Result<usize> { ... }
}

The Read trait allows for reading bytes from a source.

The Read trait is derived from Rust’s std library.

Required Methods

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

Provided Methods

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize>

Read all bytes until EOF in this source, appending them to buf.

If successful, this function returns the number of bytes which were read and appended to buf.
