Trait TailReadBytes

pub trait TailReadBytes: ReadBytes {
    // Required methods
    fn peek_tail<F, R>(&mut self, n: usize, f: F) -> Result<R>
       where F: FnOnce(&[u8]) -> Result<R>;
    fn advance_tail(&mut self, n: usize);

    // Provided method
    fn read_tail<F, R>(&mut self, n: usize, f: F) -> Result<R>
       where F: FnOnce(&[u8]) -> Result<R> { ... }
}

Trait for reading from the tail of byte buffer

Required Methods

fn peek_tail<F, R>(&mut self, n: usize, f: F) -> Result<R>

where F: FnOnce(&[u8]) -> Result<R>,

fn advance_tail(&mut self, n: usize)

Advance buffer head by n bytes. n should be smaller than remaining buffer size.

Provided Methods

fn read_tail<F, R>(&mut self, n: usize, f: F) -> Result<R>

where F: FnOnce(&[u8]) -> Result<R>,

Get n bytes from the beginning of buffer, advance by n bytes

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
