## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 100, release rhythm 35, longevity 100
- inputs: {"age_days": 3351, "days_push": 0, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A native Rust encoder and decoder for TOML-formatted files and streams, providing serde Serialize/Deserialize support. The repository also includes companion crates like toml_edit for format-preserving editing and toml_parser/toml_writer for low-level access.

## Use cases
- parse toml config files in rust
- deserialize toml into rust structs with serde
- edit toml files while preserving formatting and comments
- serialize rust structs to toml
- read cargo-style configuration files

## When to choose
- you need serde-compatible TOML parsing or serialization in Rust
- you need format-preserving TOML editing via toml_edit
- you need a no_std-capable TOML implementation

## When to avoid
- you need a general-purpose config format beyond TOML
- you are not working in Rust

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser, developer-tools
- domain: developer-tools, files, parsers
- platform: rust, cross-platform
- tags: toml, serde, format-preserving-editing, no-std, configuration-format
