cargo new

NAME

cargo-new - Create a new Cargo package

SYNOPSIS

cargo new [OPTIONS] PATH

DESCRIPTION

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).

The "authors" field in the manifest is determined from the environment or configuration settings. A name is required and is determined from (first match wins):

  • cargo-new.name Cargo config value

  • CARGO_NAME environment variable

  • GIT_AUTHOR_NAME environment variable

  • GIT_COMMITTER_NAME environment variable

  • user.name git configuration value

  • USER environment variable

  • USERNAME environment variable

  • NAME environment variable

The email address is optional and is determined from:

  • cargo-new.email Cargo config value

  • CARGO_EMAIL environment variable

  • GIT_AUTHOR_EMAIL environment variable

  • GIT_COMMITTER_EMAIL environment variable

  • user.email git configuration value

  • EMAIL environment variable

See the reference for more information about configuration files.

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

OPTIONS

New Options

--bin

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

--lib

Create a package with a library target (src/lib.rs).

--edition EDITION

Specify the Rust edition to use. Default is 2018. Possible values: 2015, 2018

--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.
