Expand description

Trait to read/seek in a source by the help of a temporarily passed mutable reference to the filesystem reader.

By requiring the user to pass the filesystem reader on every read, we circumvent the problems associated with permanently holding a mutable reference. If we held one, we could not read from two objects in alternation.

Required Methods§

source

fn read<T>(&mut self, fs: &mut T, buf: &mut [u8]) -> Result<usize>where T: Read + Seek,

See std::io::Read::read.

source

fn seek<T>(&mut self, fs: &mut T, pos: SeekFrom) -> Result<u64>where T: Read + Seek,

See std::io::Seek::seek.

source

fn stream_position(&self) -> u64

See std::io::Seek::stream_position.

Provided Methods§

source

fn read_exact<T>(&mut self, fs: &mut T, buf: &mut [u8]) -> Result<()>where T: Read + Seek,

See std::io::Read::read_exact.
