Logger Fragments

• LoggerFragment
  A fragment of a log message.
• LoggerFragmentBuilder
  A result builder for creating logger fragments in a declarative way.
• FragmentOutput
  The output of a LoggerFragment, including some intermediary state used for things like deduplicating separators.
• IfMaxLevelFragment
  Make the current fragment conditional, only calling its output method if the record’s loggerLevel is maxLevel or lower
• AndFragment
  Combine the current fragment with another, which will be written after the current fragment finishes.
• OptionalFragment
  A fragment that conditionally includes another fragment.
• ArrayFragment
  A fragment that combines multiple fragments of the same type.
• LabelFragment
  Writes the label of the logger, and requests a separator for the next fragment.
• LevelFragment
  Writes the level of the logged message, and requests a separator for the next fragment.
• LiteralFragment
  Writes the given text to the output.
• SeparatorFragment
• SpacedFragment
  A fragment that wraps another fragment, automatically separating its components with spaces.
• MessageFragment
  Writes the logged message to the output, and requests a separator for the next fragment.
• MetadataFragment
  Writes the combined metadata to the output, and requests a separator for the next fragment only if the metadata was not empty.
• SourceLocationFragment
  Writes the file location of the logged message, including the line.
• LoggerSourceFragment
  Writes the source of the logged message.
• TimestampSource
  A protocol to allow mocking the timestamp for tests
• SystemTimestampSource
  The default TimestampSource, which gets the time from the system.
• TimestampFragment
  Writes a formatted timestamp based on the time obtained from the TimestampSource.
• DefaultLoggerFragmentType
  The type of the default LoggerFragment.
• TimestampDefaultLoggerFragmentType
  The type of the default LoggerFragment with a timestamp.

Miscellaneous

• LogRecord
  Information about a specific log message, including information from the logger the message was logged to.
• ConsoleLoggerPrinter
  Defines a printer used by a ConsoleLogger to output log messages.
• DefaultConsoleLoggerPrinter
