cargo-new - Create a new Cargo package
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
<https://doc.rust-lang.org/cargo/reference/config.html> for more
information about configuration files.
See cargo-init(1) for a similar command which will create a
new manifest in an existing directory.
--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
<https://doc.rust-lang.org/cargo/reference/config.html>. 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.
-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
<https://doc.rust-lang.org/cargo/reference/config.html>.
-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 <https://doc.rust-lang.org/cargo/reference/config.html>.
+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 <https://github.com/rust-lang/rustup/> 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
<https://doc.rust-lang.org/cargo/reference/environment-variables.html>
for details on environment variables that Cargo reads.
