Trait amq_protocol::frame::BackToTheBuffer

pub trait BackToTheBuffer: Write {
    // Required method
    fn reserve_write_use<Tmp, Gen, Before>(
        s: WriteContext<Self>,
        reserved: usize,

}

Trait for Write types that allow skipping and reserving a slice, then writing some data, then write something in the slice we reserved using the return for our data write.
