source: Option<Source>

The source of the package, e.g. crates.io or None for local projects.

description: Option<String>

Description as given in the Cargo.toml

dependencies: Vec<Dependency>

List of dependencies of this particular package

license: Option<String>

License as given in the Cargo.toml

license_file: Option<PathBuf>

If the package is using a nonstandard license, this key may be specified instead of license, and must point to a file relative to the manifest.

targets: Vec<Target>

Targets provided by the crate (lib, bin, example, test, ...)

features: HashMap<String, Vec<String>>

Features provided by the crate, mapped to the features required by that feature.

manifest_path: PathBuf

Path containing the Cargo.toml

categories: Vec<String>

Categories as given in the Cargo.toml

keywords: Vec<String>

Keywords as given in the Cargo.toml

readme: Option<PathBuf>

Readme as given in the Cargo.toml

repository: Option<String>

Repository as given in the Cargo.toml

edition: String

Default Rust edition for the package

Beware that individual targets may specify their own edition in Target::edition.

metadata: Value

Contents of the free form package.metadata section

This contents can be serialized to a struct using serde:

use serde::Deserialize;
use serde_json::json;

#[derive(Debug, Deserialize)]
struct SomePackageMetadata {
    some_value: i32,
}

fn main() {
    let value = json!({
        "some_value": 42,
    });

    let package_metadata: SomePackageMetadata = serde_json::from_value(value).unwrap();
    assert_eq!(package_metadata.some_value, 42);
}

links: Option<String>

The name of a native library the package is linking to.

publish: Option<Vec<String>>

List of registries to which this package may be published.

Publishing is unrestricted if None, and forbidden if the Vec is empty.

This is always None if running with a version of Cargo older than 1.39.
