Do docs look OK now? |

Yeah, looks good. Just wrap the comment to 80 columns and I'll merge. |

Done |

Note: I changed signature of as_str to take self by-value, because Signal is Copy |

1138: Add Signal::as_str() to get representation as static string r=asomers a=MikailBag # Motivation Currently string representation of signal can be obtained with AsRef<str> impl. But it has downside: returned string's lifetime is bound to lifetime of signal, so &str must be converted to String. This allocation is avoidable, because as_ref() only returns static strings. To fix this problem, my PR adds Signal::as_str() method, which returns static string. Co-authored-by: Mikail Bagishov <bagishov.mikail@yandex.ru>

Motivation
Currently string representation of signal can be obtained with AsRef impl.
But it has downside: returned string's lifetime is bound to lifetime of signal, so &str must be converted to String. This allocation is avoidable, because as_ref() only returns static strings. To fix this problem, my PR adds Signal::as_str() method, which returns static string.
