Expand description

Blocking seek within streams.

This trait is the embedded-io equivalent of [std::io::Seek].

Required Methods§

source

fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>

Seek to an offset, in bytes, in a stream.

Provided Methods§

source

fn rewind(&mut self) -> Result<(), Self::Error>

Rewind to the beginning of a stream.

source

fn stream_position(&mut self) -> Result<u64, Self::Error>

Returns the current seek position from the start of the stream.
