## プロジェクトの歴史と使われ方

cargo-features-manager is a Rust Cargo helper that provides a terminal UI for enabling, disabling, and pruning dependency features in Cargo.toml. It focuses on a pain point that appears once Rust projects accumulate optional dependencies and feature-driven configuration.

### プロジェクトの歴史

The GitHub repository was created in April 2023 and the crate was published on crates.io days later. The README describes a TUI-like CLI that lets users view available dependency features and toggle them, with changes written directly back to Cargo.toml.

The README now states that the project has moved to Tangled, while crates.io metadata also lists Tangled as the homepage and repository. The GitHub repository remains the documentation URL supplied by the package input, but the upstream project identity has shifted.

### 採用の歴史

Adoption is specialized but visible: the supplied package-manager facts list Homebrew and Nix packages, and crates.io records tens of thousands of downloads. It serves maintainers who tune feature flags more often than the average Cargo user.

The addition of `cargo features prune`, documented in the README, moves the tool beyond manual toggling toward automated feature minimization with safeguards for known false positives.

### 使われ方

Users run `cargo features` in a project root to open a dependency selector and feature selector, then toggle features with keyboard navigation. `cargo features -d <dependency>` jumps directly to a dependency's feature selector.

`cargo features prune` attempts to disable features not required for compilation, with flags such as `--dry-run`, `--only-dependency`, `--skip-tests`, and a Cargo.toml `cargo-features-manager.keep` section for features that should be preserved.

### パッケージ好きにとっての重要性

cargo-features-manager is notable because Cargo feature sets are one of Rust packaging's more subtle sources of compile time, dependency surface, and behavior changes. A TUI for toggling and pruning features makes that metadata more inspectable than hand-editing arrays in Cargo.toml.

Its false-positive list and keep configuration show the hard part of feature minimization: not every unused-looking feature is semantically safe to remove.

### タイムライン

- 2023: ToBinio/cargo-features-manager GitHub repository created.
- 2023: cargo-features-manager crate first published on crates.io.
- 2026: crates.io metadata points homepage and repository fields at Tangled and shows the 0.12.0 release line.

### Related projects

- Cargo.toml is the manifest edited by cargo-features-manager.
- Cargo features and optional dependencies are the package metadata concepts the tool visualizes and edits.
- Tangled is the current upstream hosting target referenced by the README and crates.io metadata.
