Struct BufViewMut

pub struct BufViewMut<'a> { /* private fields */ }

A BufferViewMut into a Buf.

A BufViewMut is constructed by Buf::buffer_view_mut, and implements BufferViewMut, providing a mutable view into the Buf from which it was constructed.

Trait Implementations

impl<'a> AsMut<[u8]> for BufViewMut<'a>
