cargo-init(1)

NAME

cargo-init - Create a new Cargo package in an existing directory

DESCRIPTION

This command will create a new Cargo manifest in the current directory. Give a path as an argument to create in the given directory.

If there are typically-named Rust source files already in the directory, those will be used. If not, then a sample src/main.rs file will be created, or src/lib.rs if --lib is passed.

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-new(1) for a similar command which will create a new package in a new directory.

OPTIONS

Init 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.

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

+toolchain: 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.
