Trait Implementations

impl<S: ReadAt> DynReadAt for ReadAtShim<S>

fn len(&mut self) -> Result<u64, BoxedError>

Total length in bytes (may be expensive; see ReadAt::len).

fn read_exact_at( &mut self, offset: u64, out: &mut [u8], ) -> Result<(), BoxedError>

Fill out with the bytes at offset.

fn read_many_at( &mut self, reqs: &mut [(u64, &mut [u8])], ) -> Result<(), BoxedError>

Fill each buffer from its offset, concurrently where possible.

fn len_hint(&self) -> Option<u64>

Total length if known without reading ahead.

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

Read up to out.len() bytes at offset; see ReadAt::read_at.

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

The whole source as one slice, when already in memory.

fn is_empty(&mut self) -> Result<bool, BoxedError>

Whether the source holds no bytes.
