impl<S: FileByteSource> FileContents for FileContentsWithChunkedCaching<S>

fn len(&self) -> u64

Must return the length, in bytes, of this file.

fn read_bytes_at(
    &self,
    offset: u64,
    size: u64
) -> FileAndPathHelperResult<&[u8]>

Must return a slice of the file contents, or an error. The slice’s lifetime must be valid for the entire lifetime of this FileContents object. This restriction may be a bit cumbersome to satisfy; it’s a restriction that’s inherited from the object crate’s ReadRef trait.

fn read_bytes_at_until(
    &self,
    range: Range<u64>,
    delimiter: u8
) -> FileAndPathHelperResult<&[u8]>

TODO: document

fn read_bytes_into(
    &self,
    buffer: &mut Vec<u8>,
    offset: u64,
    size: u64
) -> FileAndPathHelperResult<()>

Append size bytes to buffer, starting to read at offset in the file.

fn is_empty(&self) -> bool

Whether the file is empty.
