Flowgger is a fast, simple and lightweight data collector.  It reads
log entries over a given protocol, extracts them, decodes them using a
given format, re-encodes them into a different format, and
asynchronously pushes the result into a remote data store.

Flowgger is designed to be:

- Paranoid: it carefully validates input data to prevent injection of
  malformed/incomplete records down the chain.
- Safe: written in Rust, without any unsafe code.
- Fast: even though messages are systematically parsed and validated,
  Flowgger is orders of magnitude faster than Logstash and Fluentd.
- Standalone: it comes as a single executable file, and doesn't require a JVM.

Flowgger supports common input types: stdin, UDP, TCP, TLS and Redis,
as well as multiple input formats: JSON (GELF), LTSV, Cap'n Proto and
RFC5424.  Normalized messages can be sent to Kafka, Graylog, to
downstream Flowgger servers, or to other log collectors for further
processing.
