cargo metadata

This tool adds ability get to metadata for a cargo project in a machine readable format (JSON or TOML).

The metadata includes information about crates, dependencies, their versions and paths.

This should be useful for Rust plugins and IDEs.

Installation

If you have a recent version of cargo (>= 0.6) you can cargo install it.

$ cargo install --git https://github.com/intellij-rust/cargo-metadata

At the moment cargo-metadata depends on the development version of cargo so it is not available on crates.io just yet.

Usage

Inside the project directory cargo metadata -f will output information like this:

  "root": {
    "name": "meta-example",
    "version": "0.1.0",
    "features": null
  },
