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).

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 config value

CARGO_NAME environment variable

GIT_AUTHOR_NAME environment variable

GIT_COMMITTER_NAME environment variable git configuration value

USER environment variable

USERNAME environment variable

NAME environment variable

The email address is optional and is determined from: Cargo config value

CARGO_EMAIL environment variable

GIT_AUTHOR_EMAIL environment variable

GIT_COMMITTER_EMAIL environment variable 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.

--edition edition

Specify the Rust edition to use. Default is 2018. 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.


Display Options

-v, --verbose

Use verbose output. May be specified twice for "very verbose" output which includes extra output such as dependency warnings and build script output. May also be specified with the term.verbose config value <>.

-q, --quiet

No output printed to stdout.

--color when

Control when colored output is used. Valid values:

auto (default): Automatically detect if color support is available on the terminal.

always: Always display colors.

never: Never display colors.

May also be specified with the term.color config value <>.


Common Options


If Cargo has been installed with rustup, and the first argument to cargo begins with +, it will be interpreted as a rustup toolchain name (such as +stable or +nightly). See the rustup documentation <> for more information about how toolchain overrides work.

-h, --help

Prints help information.

-Z flag

Unstable (nightly-only) flags to Cargo. Run cargo -Z help for details.


See the reference <> for details on environment variables that Cargo reads.
