Opaque type for an operations log that provides fast O(1) appends.

# Documentation

An efficiently catenable sequence of log entries.

#### Instances

Semigroup Log Source # | |

Monoid Log Source # | |

(Applicative m, Monad m) => MonadLogger (WriterT Log m) Source # | |

(Applicative m, Monad m) => MonadLogger (RWST r Log s m) Source # | |

(Applicative m, Monad m) => MonadLogger (RWST r Log s m) Source # | |

toText :: Log -> Text Source #

Transform a log into text. Every log entry becomes its own line (or possibly more, in case of multi-line entries).

Typeclass for things that can be turned into a single-entry log.

class (Applicative m, Monad m) => MonadLogger m where Source #

Typeclass for monads that support logging.

logMsg :: ToLog a => a -> m () Source #

Add one log entry.

addLog :: Log -> m () Source #

Append an entire log.

#### Instances

Monad m => MonadLogger (DistNestT lore m) Source # | |

(Applicative m, Monad m) => MonadLogger (RWST r Log s m) Source # | |

(Applicative m, Monad m) => MonadLogger (RWST r Log s m) Source # | |
