Prometheus meets Serde

This crate is a Rust library for Prometheus labels. It is built upon Serde, a high performance generic serialization framework.


This crate works with Cargo and can be found on crates.io with a Cargo.toml like:

serde_prometheus_labels = "0.2"

The documentation is available on docs.rs.

Bridge to prometheus-client

With the feature "bridge" enabled, this crate provides a wrapper to prometheus_client::metrics::family::Family which uses serde::Serialize instead of prometheus_client::encoding::text::Encode to encode the label set used by this family. The bridge is available directly at the root of the crate as serde_prometheus_labels::Family.
