cargo-new - Create a new Cargo package


cargo new [options] path


This command will create a new Cargo package in the given directory. This includes a simple template with a Cargo.toml manifest, sample source file, and a VCS ignore file. If the directory is not already in a VCS repository, then a new repository is created (see --vcs below).

See cargo-init(1) for a similar command which will create a new manifest in an existing directory.


New Options

Create a package with a binary target (src/ This is the default behavior.

--edition edition
Specify the Rust edition to use. Default is 2021. Possible values: 2015, 2018, 2021
--name name
Set the package name. Defaults to the directory name.
--vcs vcs
Initialize a new VCS repository for the given version control system (git, hg, pijul, or fossil) or do not initialize any version control at all (none). If not specified, defaults to git or the configuration value cargo-new.vcs, or none if already inside a VCS repository.
--registry registry
This sets the publish field in Cargo.toml to the given registry name which will restrict publishing only to that registry.

Registry names are defined in Cargo config files. If not specified, the default registry defined by the registry.default config key is used. If the default registry is not set and --registry is not used, the publish field will not be set which means that publishing will not be restricted.
