Function x11rb_protocol::xauth::file::read_entry

fn read_entry<R: Read>(read: &mut R) -> Result<Option<AuthEntry>, Error>

Read a single entry from an ~/.Xauthority file.

This function tries to return Ok(None) when the end of the file is reached. However, the code also treats a single byte as ‘end of file’, because things were simpler to implement like this.
