Trait baffa::WriteBuf

pub trait WriteBuf: Buf {
    unsafe fn advance(&mut self, step: usize);
    unsafe fn write(&mut self, ptr: *const u8, size: usize);

    fn remaining(&self) -> usize { ... }
    fn write_slice(&mut self, bytes: &[u8]) -> usize { ... }
}

Describes write-able buffer

Required methods

unsafe fn advance(&mut self, step: usize)

Moves cursor, considering bytes written.

unsafe fn write(&mut self, ptr: *const u8, size: usize)

Low level write method, which copies data from pointer up to size.

This function is always used in safe manner by other default implementations:

• size is always min(buffer_size, available)
• ptr is always non-null.

Provided methods

fn remaining(&self) -> usize

Returns number of bytes left

Default implementation returns capacity - len

fn write_slice(&mut self, bytes: &[u8]) -> usize

Writes supplied slice into the buffer, returning number of written bytes.

Allows partial writes.
