Trait BufferWriter

pub trait BufferWriter: DerefMut<Target = [u8]> {
    // Required methods
    fn commit(&self, n: usize) -> Result<(), BufferError>;
    fn remaining_capacity(&self) -> usize;

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

A Writer to write to a Buffer as it is a writeable slice

Required Methods

fn commit(&self, n: usize) -> Result<(), BufferError>

After writing th bytes to self the user must tell teh buffer how many bytes have bee written. This increases the write_position of the buffer by n

fn remaining_capacity(&self) -> usize

Return the number of bytes that can be written without an error

Provided Methods

fn has_remaining_capacity(&self) -> bool

Returns true if the writer has remaining capacity to write to
