string used to tag the record
timestamp of the event being logged
data to be packed via msgpack and sent
True if the data was successfully sent to the fluent server. False if the data was queued for sending later but no attempt was made to send to the remote host because of a previous error.
write
Pack the given record using MessagePack and write it with the given timestamp using $(D_PSYMBOL write).
If a prefix was given when the logger was created the tag is appended to the prefix when posting. This allocation may be avoided by giving a $(D_KEYWORD null) prefix in the constructor and the full tag here.
