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 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/guide/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.

       --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>.

   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.

       -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.
