cargo - The Rust package manager
cargo [OPTIONS] COMMAND
[ARGS]
cargo [OPTIONS] --version
cargo [OPTIONS] --list
cargo [OPTIONS] --help
cargo [OPTIONS] --explain CODE
This program is a package manager and build tool for the Rust
language, available at <https://rust-lang.org>.
-V, --version
Print version info and exit. If used with
--verbose, prints extra information.
--list
List all installed Cargo subcommands. If used with
--verbose, prints extra information.
--explain CODE
Run rustc --explain CODE which will print out a
detailed explanation of an error message (for example, E0004).
-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>.
--frozen, --locked
Either of these flags requires that the
Cargo.lock
file is up-to-date. If the lock file is missing, or it needs to be updated,
Cargo will exit with an error. The
--frozen flag also prevents Cargo
from attempting to access the network to determine if it is out-of-date.
These may be used in environments where you want to assert that
the Cargo.lock file is up-to-date (such as a CI build) or want to
avoid network access.
--offline
Prevents Cargo from accessing the network for any reason.
Without this flag, Cargo will stop with an error if it needs to access the
network and the network is not available. With this flag, Cargo will attempt
to proceed without the network if possible.
Beware that this may result in different dependency resolution
than online mode. Cargo will restrict itself to crates that are downloaded
locally, even if there might be a newer version as indicated in the local
copy of the index. See the cargo-fetch(1) command to download
dependencies before going offline.
May also be specified with the net.offline config
value <https://doc.rust-lang.org/cargo/reference/config.html>.
-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.
0
Cargo succeeded.
101
Cargo failed to complete.
~/.cargo/
Default location for Cargo’s "home"
directory where it stores various files. The location can be changed with the
CARGO_HOME environment variable.
$CARGO_HOME/bin/
Binaries installed by
cargo-install(1) will be
located here. If using rustup, executables distributed with Rust are also
located here.
$CARGO_HOME/config
The global configuration file. See the reference
<https://doc.rust-lang.org/cargo/reference/config.html> for more
information about configuration files.
.cargo/config
Cargo automatically searches for a file named
.cargo/config in the current directory, and all parent directories.
These configuration files will be merged with the global configuration
file.
$CARGO_HOME/credentials
Private authentication information for logging in to a
registry.
$CARGO_HOME/registry/
This directory contains cached downloads of the registry
index and any downloaded dependencies.
$CARGO_HOME/git/
This directory contains cached downloads of git
dependencies.
Please note that the internal structure of the $CARGO_HOME
directory is not stable yet and may be subject to change.
1.Build a local package and all of its dependencies:
2.Build a package with optimizations:
3.Run tests for a cross-compiled target:
cargo test --target i686-unknown-linux-gnu
4.Create a new package that builds an executable:
5.Create a package in the current directory:
mkdir foo && cd foo
cargo init .
