The [package] section of the Manifest. This is where crate properties are.

Note that most of these properties can be inherited from a workspace, and therefore not available just from reading a single Cargo.toml. See Manifest::inherit_workspace.

You can replace Metadata generic type with your own to parse into something more useful than a generic toml Value

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

Careful: some names are uppercase, case-sensitive. - changes to _ when used as a Rust identifier.

edition: Inheritable<Edition>

Package’s edition opt-in.

rust_version: Option<Inheritable<String>>

MSRV 1.x (beware: does not require semver formatting)

version: Inheritable<String>

Must parse as semver, e.g. “1.9.0”

build: Option<OptionalFile>

Build script definition

workspace: Option<String>

Workspace this package is a member of (None if it’s implicit)

authors: Inheritable<Vec<String>>

e.g. [“Author e@mail”, “etc”] Deprecated.

links: Option<String>

description: Option<Inheritable<String>>

A short blurb about the package. This is not rendered in any format when uploaded to crates.io (aka this is not markdown).

homepage: Option<Inheritable<String>>

Project’s homepage

documentation: Option<Inheritable<String>>

Path to your custom docs. Unnecssary if you rely on docs.rs.

readme: Inheritable<OptionalFile>

This points to a file under the package root (relative to this Cargo.toml). implied if README.md, README.txt or README exists.

keywords: Inheritable<Vec<String>>

Up to 5, for search

categories: Inheritable<Vec<String>>

This is a list of up to five categories where this crate would fit. e.g. ["command-line-utilities", "development-tools::cargo-plugins"]

exclude: Inheritable<Vec<String>>

Don’t publish these files

include: Inheritable<Vec<String>>

Publish these files

license: Option<Inheritable<String>>

e.g. “MIT”

license_file: Option<Inheritable<PathBuf>>

If license is not standard

repository: Option<Inheritable<String>>

(HTTPS) URL to crate’s repository

default_run: Option<String>

The default binary to run by cargo run.

autobins: bool

Discover binaries from the file system

autoexamples: bool

Discover examples from the file system

autotests: bool

Discover tests from the file system

autobenches: bool

Discover benchmarks from the file system

publish: Inheritable<Publish>

Disable publishing or select custom registries.

resolver: Option<Resolver>

“2” is the only useful value

metadata: Option<Metadata>

Arbitrary metadata of any type, an extension point for 3rd party tools.

Trait Implementations

impl<Metadata: Clone> Clone for Package<Metadata>

fn clone(&self) -> Package<Metadata>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Metadata: Debug> Debug for Package<Metadata>

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

Formats the value using the given formatter.

impl<Metadata: Default> Default for Package<Metadata>

fn default() -> Self

Returns the “default value” for a type.

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

where Metadata: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Metadata: PartialEq> PartialEq for Package<Metadata>

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

This method tests for self and other values to be equal, and is used by ==.

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