license-retriever

Retrieves licenses of all Rust dependencies. Originally written for stencil2 but is now separated into its own project.

How

Licenses are retrieved by searching in the following order:

• Folder that Cargo.toml is in
• Crate cache in ~/.cargo
• GitHub repository
• Text from spdx with identifier in Cargo.toml

Usage

Cargo

cargo add license-retriever
cargo add --build license-retriever

build.rs

use license_retriever::{Config, LicenseRetriever};

fn main() {
    let config = Config {
        // options...
        ..Config::default()
    };
    LicenseRetriever::from_config(&config).unwrap().save_in_out_dir("LICENSE-3RD-PARTY").unwrap();
}

main.rs

use license_retriever;

fn main() {
    let licenses = license_retriever::license_retriever_data!("LICENSE-3RD-PARTY").unwrap();
    println!("{}", licenses);
}
