One or more crates described by a single Cargo.toml

Each target of a Package will be built as a crate. For more information, see https://doc.rust-lang.org/book/ch07-01-packages-and-crates.html.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Name as given in the Cargo.toml

version: Version

Version given in the Cargo.toml

authors: Vec<String>

Authors given in the Cargo.toml

id: PackageId

An opaque identifier for a package

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<Utf8PathBuf>

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: Utf8PathBuf

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<Utf8PathBuf>

Readme as given in the Cargo.toml

repository: Option<String>

Repository as given in the Cargo.toml

homepage: Option<String>

Homepage as given in the Cargo.toml

On versions of cargo before 1.49, this will always be None.

documentation: Option<String>

Documentation URL as given in the Cargo.toml

On versions of cargo before 1.49, this will always be None.

edition: Edition

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.

default_run: Option<String>

The default binary to run by cargo run.

This is always None if running with a version of Cargo older than 1.55.

rust_version: Option<VersionReq>

The minimum supported Rust version of this package.

This is always None if running with a version of Cargo older than 1.58.

Implementations

impl Package

pub fn license_file(&self) -> Option<Utf8PathBuf>

Full path to the license file if one is present in the manifest

pub fn readme(&self) -> Option<Utf8PathBuf>

Full path to the readme file if one is present in the manifest

Trait Implementations

impl Clone for Package

fn clone(&self) -> Package

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Package

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Package

fn deserialize<__D>( __deserializer: __D, ) -> Result<Package, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Package

fn eq(&self, other: &Package) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Package

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Package

impl StructuralPartialEq for Package
