Trait Reader 

pub trait Reader<T>: Iterator {
    // Required methods
    fn len(&self) -> usize;
    fn pos(&self) -> usize;
    fn rollback(&mut self, amount: usize) -> Result<(), ()>;
    fn try_read(&mut self, amount: usize) -> Option<T>;

    // Provided method
    fn is_end(&self) -> bool { ... }
}

Provides a way to effectively read an object piece by piece.

Required Methods

fn len(&self) -> usize

Length of the object being read

fn pos(&self) -> usize

Current index position of the reader

fn rollback(&mut self, amount: usize) -> Result<(), ()>

Reads back several pieces

fn try_read(&mut self, amount: usize) -> Option<T>

Reads several pieces and encapsulates into one object

Provided Methods

fn is_end(&self) -> bool

Whether the reader has reached the end of the object

Dyn Compatibility

This trait is dyn compatible.

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