cargo-init - Create a new Cargo package in an existing
directory
cargo init [options] [path]
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).
See cargo-new(1) for a similar command which will create a
new package in a new 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 2021.
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
<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://rust-lang.github.io/rustup/overrides.html> 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.
