CARGO-FETCH(1)		    General Commands Manual		CARGO-FETCH(1)

NAME
       cargo-fetch — Fetch dependencies of a package from the network

SYNOPSIS
       cargo fetch [options]

DESCRIPTION
       If a Cargo.lock file is available, this command will ensure that all of
       the git dependencies and/or registry dependencies are downloaded and
       locally available. Subsequent Cargo commands will be able to run
       offline after a cargo fetch unless the lock file changes.

       If the lock file is not available, then this command will generate the
       lock file before fetching the dependencies.

       If --target is not specified, then all target dependencies are fetched.

       See also the cargo-prefetch <https://crates.io/crates/cargo-prefetch>
       plugin which adds a command to download popular crates. This may be
       useful if you plan to use Cargo without a network with the --offline
       flag.

OPTIONS
   Fetch options
       --target triple
	   Fetch for the given architecture. The default is all architectures.
	   The general format of the triple is
	   <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
	   a list of supported targets. This flag may be specified multiple
	   times.

	   This may also be specified with the build.target config value
	   <https://doc.rust-lang.org/cargo/reference/config.html>.

	   Note that specifying this flag makes Cargo run in a different mode
	   where the target artifacts are placed in a separate directory. See
	   the build cache
	   <https://doc.rust-lang.org/cargo/reference/build-cache.html>
	   documentation for more details.

   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
	   <https://doc.rust-lang.org/cargo/reference/config.html>.

       -q, --quiet
	   Do not print cargo log messages.  May also be specified with the
	   term.quiet config value
	   <https://doc.rust-lang.org/cargo/reference/config.html>.

       --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>.

   Manifest Options
       --manifest-path path
	   Path to the Cargo.toml file. By default, Cargo searches for the
	   Cargo.toml file in the current directory or any parent directory.

       --locked
	   Asserts that the exact same dependencies and versions are used as
	   when the existing Cargo.lock file was originally generated. Cargo
	   will exit with an error when either of the following scenarios
	   arises:

	   •   The lock file is missing.

	   •   Cargo attempted to change the lock file due to a different
	       dependency resolution.

	   It may be used in environments where deterministic builds are
	   desired, such as in CI pipelines.

       --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.

	   May also be specified with the net.offline config value
	   <https://doc.rust-lang.org/cargo/reference/config.html>.

       --frozen
	   Equivalent to specifying both --locked and --offline.

       --lockfile-path PATH
	   Changes the path of the lockfile from the default
	   (<workspace_root>/Cargo.lock) to PATH. PATH must end with
	   Cargo.lock (e.g. --lockfile-path
	   /tmp/temporary-lockfile/Cargo.lock). Note that providing
	   --lockfile-path will ignore existing lockfile at the default path,
	   and instead will either use the lockfile from PATH, or write a new
	   lockfile into the provided PATH if it doesn’t exist.	 This flag can
	   be used to run most commands in read-only directories, writing
	   lockfile into the provided PATH.

	   This option is only available on the nightly channel
	   <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
	   requires the -Z unstable-options flag to enable (see #14421
	   <https://github.com/rust-lang/cargo/issues/14421>).

   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
	   <https://rust-lang.github.io/rustup/overrides.html> for more
	   information about how toolchain overrides work.

       --config KEY=VALUE or PATH
	   Overrides a Cargo configuration value. The argument should be in
	   TOML syntax of KEY=VALUE, or provided as a path to an extra
	   configuration file. This flag may be specified multiple times.  See
	   the command-line overrides section
	   <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
	   for more information.

       -C PATH
	   Changes the current working directory before executing any
	   specified operations. This affects things like where cargo looks by
	   default for the project manifest (Cargo.toml), as well as the
	   directories searched for discovering .cargo/config.toml, for
	   example. This option must appear before the command name, for
	   example cargo -C path/to/my-project build.

	   This option is only available on the nightly channel
	   <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
	   requires the -Z unstable-options flag to enable (see #10098
	   <https://github.com/rust-lang/cargo/issues/10098>).

       -h, --help
	   Prints help information.

       -Z flag
	   Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
	   details.

ENVIRONMENT
       See the reference
       <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
       for details on environment variables that Cargo reads.

EXIT STATUS
       •   0: Cargo succeeded.

       •   101: Cargo failed to complete.
