Trait Implementations

impl<'a> Clone for MmapBackend<'a>

fn clone(&self) -> MmapBackend<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for MmapBackend<'a>

impl<'a> Debug for MmapBackend<'a>

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

Formats the value using the given formatter.

impl<'a> From<MmapBackend<'a>> for ReadBackend<'a>

Available on crate feature mmap only.

fn from(mmap: MmapBackend<'a>) -> Self

Converts to this type from the input type.

impl MediaReadAt for MmapBackend<'_>

Available on crate feature mmap only.

fn len_u64(&self) -> u64

Total length of the source in bytes.

fn read_at( &self, range: ByteRange, dst: &mut [u8], ) -> Result<usize, ReadAtError>

Copy exactly range.len bytes into dst.

fn window_at(&self, range: ByteRange) -> Result<&[u8], ReadAtError>

Borrow exactly range.len bytes from the source.

fn window_at_partial(&self, range: ByteRange) -> Result<&[u8], ReadAtError>

Borrow up to range.len bytes. The offset must still be in bounds.

fn as_contiguous(&self) -> Option<&[u8]>

Return the complete contiguous source only for compatibility paths.
