Struct LogSink 

pub struct LogSink { /* private fields */ }

Reads a daemon’s output on stdin and writes it to the log store

Spawned by the supervisor as a sibling of the daemon, holding the read end of the daemon’s output pipe. Keeping the reader in its own process is what makes logging survive a supervisor crash: the pipe still has a reader, so the daemon is neither killed by SIGPIPE nor blocked, and no output is lost. Exits when the pipe reaches end of file, which happens once the daemon and every descendant holding the write end have gone.
