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

NAME

cargo-vendor — Vendor all dependencies locally

SYNOPSIS

cargo vendor [options] [path]

DESCRIPTION

This cargo subcommand will vendor all crates.io and git dependencies for a project into the specified directory at <path>. After this command completes the vendor directory specified by <path> will contain all remote sources from dependencies specified. Additional manifests beyond the default one can be specified with the -s option.

The configuration necessary to use the vendored sources would be printed to stdout after cargo vendor completes the vendoring process. You will need to add or redirect it to your Cargo configuration file, which is usually .cargo/config.toml locally for the current package.

Cargo treats vendored sources as read-only as it does to registry and git sources. If you intend to modify a crate from a remote source, use [patch] or a path dependency pointing to a local copy of that crate. Cargo will then correctly handle the crate on incremental rebuilds, as it knowns that it is no longer a read-only dependency.

OPTIONS

Vendor Options

-s manifest, --sync manifest

Specify an extra Cargo.toml manifest to workspaces which should also be vendored and synced to the output. May be specified multiple times.

--no-delete

Don’t delete the “vendor” directory when vendoring, but rather keep all existing contents of the vendor directory

--respect-source-config

Instead of ignoring [source] configuration by default in .cargo/config.toml read it and use it when downloading crates from crates.io, for example

--versioned-dirs

Normally versions are only added to disambiguate multiple versions of the same package. This option causes all directories in the “vendor” directory to be versioned, which makes it easier to track the history of vendored packages over time, and can help with the performance of re-vendoring when only a subset of the packages have changed.

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. 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>.

--frozen

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

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>.

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.

EXAMPLES

1.Vendor all dependencies into a local “vendor” folder 

cargo vendor

2.Vendor all dependencies into a local “third-party/vendor” folder 

cargo vendor third-party/vendor

3.Vendor the current workspace as well as another to “vendor” 

cargo vendor -s ../path/to/Cargo.toml

4.Vendor and redirect the necessary vendor configs to a config file. 

cargo vendor > path/to/my/cargo/config.toml
