Trait Implementations

impl Debug for ExternalMapping

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MappedRegion for ExternalMapping

fn as_ptr(&self) -> *mut u8

used for passing this region to ioctls for setting guest memory.

fn size(&self) -> usize

Returns the size of the memory region in bytes.

fn add_fd_mapping( &mut self, _offset: usize, _size: usize, _fd: &dyn AsRawDescriptor, _fd_offset: u64, _prot: Protection ) -> Result<()>

Maps size bytes starting at fd_offset bytes from within the given fd at offset bytes from the start of the region with prot protections. offset must be page aligned.

fn remove_mapping(&mut self, _offset: usize, _size: usize) -> Result<()>

Remove size-byte mapping starting at offset.

impl PartialEq for ExternalMapping

fn eq(&self, other: &ExternalMapping) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
