Function Metrics

This project is divided in a build time module (metrics-fn-codegen), and a runtime module (metrics-fn).

Simply include metrics-fn as a dependency and configure the features for the desired metric recorders to start using it.

For example, to enable collecting Prometheus metrics, use the following:

metrics-fn = { version = "0.1", features = [ "record-prometheus" ] }

For more info about the available recorders and usage, see PENDING.

Code Style

Configure a pre-commit hook so you don't have to worry about it ever again:

$ ln -sr pre-commit .git/hooks/pre-commit

A nightly profile is also required. Ensure you have one installed by running:

$ rustup show
Default host: x86_64-unknown-linux-gnu
rustup home:  /home/user/.rustup
