_SWIMPrettyMetadataLogHandler

public struct _SWIMPrettyMetadataLogHandler : LogHandler

Pretty log formatter which prints log lines in the following multi line format, listing every metadata element in it’s own, //-prefixed, line as well as pretty printing connections if set as Logger.MetadataValue.

Example output:

 SWIMNIOSample: [2020-08-25 0:7:59.8420] [info] [Example.swift:66] Membership status changed: [udp://127.0.0.1:7001#7015602685756068157] is now [alive(incarnation: 0)]
/ metadata:
/ "swim/member": udp://127.0.0.1:7001#7015602685756068157
/ "swim/member/previousStatus": unknown
/ "swim/member/status": alive(incarnation: 0)

Pro tip: you may want to use a coloring terminal application, which colors lines prefixed with // with a slightly different color, which makes visually parsing metadata vs. log message lines even more visually pleasing.
