Trait Implementations§

impl BufferHandle for VirtioObjectHandle
source§fn try_clone(&self) -> Result<Self, Error>
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.
source§fn get_mapping(
&self,
offset: usize,
size: usize
) -> Result<MemoryMappingArena, MmapError>
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.Auto Trait Implementations§
