Trait Implementations

impl ByteSource for UrlSource

fn prefetch(&self, _ranges: &[Range<u64>])

Left as a no-op. Coalescing the R-tree’s leaves into multi-range requests is worth measuring before it is worth writing.

fn path(&self) -> &str

Path or URL this reads, for error messages.

fn len(&self) -> Result<u64>

Total length in bytes.

fn read_at(&self, offset: u64, len: usize) -> Result<Bytes>

Read up to len bytes at offset, returning fewer at end of file.

fn close(&self)

Release the underlying handle. Idempotent; reads after it fail with Error::Closed.

fn is_empty(&self) -> Result<bool>

fn read_exact_at(&self, offset: u64, len: usize) -> Result<Bytes>

Read exactly len bytes at offset; a short read is Error::Corrupt.

fn read_to_end(&self, offset: u64) -> Result<Bytes>

Read from offset to end of file.

impl Debug for UrlSource

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

Formats the value using the given formatter.
