Trait Buffer 

pub trait Buffer: AsRef<[u8]> + AsMut<[u8]> {
    // Required methods
    fn extend_from_slice(&mut self, other: &[u8]) -> Result<()>;
    fn truncate(&mut self, len: usize);

    // Provided methods
    fn len(&self) -> usize { ... }
    fn is_empty(&self) -> bool { ... }
}

In-place encryption/decryption byte buffers.

This trait defines the set of methods needed to support in-place operations on a Vec-like data type.

Required Methods

fn extend_from_slice(&mut self, other: &[u8]) -> Result<()>

Extend this buffer from the given slice.

Errors

If the buffer has insufficient capacity.

fn truncate(&mut self, len: usize)

Truncate this buffer to the given size.

Provided Methods

fn len(&self) -> usize

Get the length of the buffer

fn is_empty(&self) -> bool

Is the buffer empty?

Dyn Compatibility

This trait is dyn compatible.

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