// `absl::LogSink` is an interface which can be extended to intercept and
// process particular messages (with `LOG.ToSinkOnly()` or
// `LOG.ToSinkAlso()`) or all messages (if registered with
// `absl::AddLogSink`).  Implementations must not take any locks that might be
// held by the `LOG` caller.
