cargo-init(1)

NAME

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

SYNOPSIS

cargo init [options] [path]

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, 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

+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.

ENVIRONMENT

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

EXIT STATUS

  • 0: Cargo succeeded.
  • 101: Cargo failed to complete.

EXAMPLES

  1. Create a binary Cargo package in the current directory:

    cargo init
