Trait Implementations

impl Source for FileSource

fn len(&self) -> u64

Total length in bytes.

fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>

Fills buf from offset; fails if the range is out of bounds.

fn is_empty(&self) -> bool

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

The whole content when it already sits in memory, so reads can borrow it.
