Trait ResizeBuffer 

pub trait ResizeBuffer:
    WriteBuffer
    + AsRef<[u8]>
    + AsMut<[u8]> {
    // Required methods
    fn buffer_insert(&mut self, pos: usize, data: &[u8]) -> Result<(), Error>;
    fn buffer_remove(&mut self, range: Range<usize>) -> Result<(), Error>;
    fn buffer_resize(&mut self, len: usize) -> Result<(), Error>;

    // Provided method
    fn buffer_extend(&mut self, len: usize) -> Result<&mut [u8], Error> { ... }
}

Support for writing to, accessing, and resizing a byte buffer

Required Methods

fn buffer_insert(&mut self, pos: usize, data: &[u8]) -> Result<(), Error>

Insert a slice at the given position in the buffer

fn buffer_remove(&mut self, range: Range<usize>) -> Result<(), Error>

Remove an exclusive range from the buffer

fn buffer_resize(&mut self, len: usize) -> Result<(), Error>

Resize the buffer, truncating or padding it with zeroes

Provided Methods

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

Extend the buffer with len bytes of zeroes and return a mutable reference to the slice

Dyn Compatibility

This trait is dyn compatible.

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