Trait Read 

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

Implementors of the Read trait are called ‘readers’.

Readers are defined by one required method, [read()]. Each call to [read()] will attempt to pull bytes from this source into a provided buffer.

Required Methods

fn capacity(&self) -> usize

Returns the number of elements the Reader can hold.

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

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

Dyn Compatibility

This trait is dyn compatible.

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