Function read_seek_table 

pub fn read_seek_table<R>(reader: &mut R) -> Result<Option<ZstdSeekTable>>
where
    R: Read + Seek,

Read the seek table from the end of a zstd seekable format stream.

Returns Ok(None) if the stream doesn’t apper to contain a seek table. Otherwise, returns Err(_) if the seek table could not be parsed or if an I/O error occurred while trying to read the seek table. If it returns Ok(_), it will also restore the reader to its original stream position.

The seek table is returned as-is from the underlying reader. No attempt is made to validate that the seek table lines up with the underlying zstd stream. This means a malformed seek table could have out-of-bounds offsets, could omit sections of the underyling stream, or could be misaligned from frames of the underlying stream.
