Trait Implementations

impl AsBufferHandle for GuestMemHandle

type BufferHandle = GuestMemHandle

fn as_buffer_handle(&self) -> &Self::BufferHandle

impl BufferHandle for GuestMemHandle

fn try_clone(&self) -> Result<Self, Error>

Try to clone this handle. This must only create a new reference to the same backing memory and not duplicate the buffer itself.

fn get_mapping( &self, offset: usize, size: usize ) -> Result<MemoryMappingArena, MmapError>

Returns a linear mapping of [offset..offset+size] of the memory backing this buffer.
