cargo-manifest

serde definitions to read and write Cargo.toml files.

Description

This Rust crate contains various structs and enums to represent the contents of a Cargo.toml file. These definitions can be used with serde and the toml crate to read and write Cargo.toml manifest files.

This crate also to some degree supports post-processing of the data to emulate Cargo's workspace inheritance and autobins features. This is used for example by crates.io to extract whether a crate contains a library or executable binaries.

[!NOTE] The cargo team regularly adds new features to the Cargo.toml file definition. This crate aims to keep up-to-date with these changes. You should keep this crate up-to-date to correctly parse all fields in modern Cargo.toml files.

Installation

cargo add cargo-manifest

Usage

use cargo_manifest::Manifest;

let manifest = Manifest::from_path("Cargo.toml").unwrap();

see docs.rs for more information.

Users

• cargo-chef
• crates.io is using this crate for server-side validation of Cargo.toml files.

Alternatives

This crate is a fork of the cargo_toml project. There are only some minor differences between these projects at this point, you will need to evaluate which one fits your needs better.

There is also cargo-util-schemas now, which is maintained by the cargo team themselves. This crate was extracted from the cargo codebase and is used inside the cargo binary itself. It is kept up-to-date with the latest changes to the Cargo.toml file format, but is currently lacking some of the post-processing features that cargo-manifest provides.
