Logfmt formatter for tracing-subscriber with opentelemetry support

Opentelemetry support

This crate is a fork of EmbarkStudios/tracing-logfmt that adds the opentelemetry trace and span id to the log output.


Logfmt is a compact and simple log format for structured logging. Each log row contains one level of key/value pairs. To keep it as compact and readable as possible, values are only quoted if needed.

key=value otherkey="value with spaces" third="with escaped \"chars\""

There is no strict standard for the format, but it was first documented in this article by Brandur Leach.
