NAME

       cargo-add - Add dependencies to a Cargo.toml manifest file

SYNOPSIS

       cargo add [options] crate...
       cargo add [options] --path path
       cargo add [options] --git url [crate...]

DESCRIPTION

       This command can add or modify dependencies.

       The source for the dependency can be specified with:

       •  crate@version: Fetch from a registry with a version constraint of "version"

       •  --path path: Fetch from the specified path

       •  --git url: Pull from a git repo at url

       If no source is specified, then a best effort will be made to select one, including:

       •  Existing dependencies in other tables (like dev-dependencies)

       •  Workspace members

       •  Latest release in the registry

       When you add a package that is already present, the existing entry will be updated with
       the flags specified.

       Upon successful invocation, the enabled (+) and disabled (-) features
       <https://doc.rust-lang.org/cargo/reference/features.md> of the specified dependency will
       be listed in the command's output.

           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories>.

       --branch branch
           Branch to use when adding from git.

       --tag tag
           Tag to use when adding from git.

           to local crate to add.

       --registry registry
           Name of the registry to use. Registry names are defined in Cargo config files
           <https://doc.rust-lang.org/cargo/reference/config.html>. If not specified, the default
           registry is used, which is defined by the registry.default config key which defaults

   Section options
       --dev
           Add as a development dependency
           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#development-dependencies>.

       --build
           Add as a build dependency
           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#build-dependencies>.

       --target target
           Add as a dependency to the given target platform
           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#platform-specific-dependencies>.
       </dl>

   Dependency options
       --rename name
           Rename
           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#renaming-dependencies-in-cargotoml>
           the dependency.

       --optional
           Mark the dependency as optional
           <https://doc.rust-lang.org/cargo/reference/features.html#optional-dependencies>.

       --no-optional
           Mark the dependency as required
           <https://doc.rust-lang.org/cargo/reference/features.html#optional-dependencies>.

       --no-default-features
           Disable the default features
           <https://doc.rust-lang.org/cargo/reference/features.html#dependency-features>.

       --default-features
           Re-enable the default features
           <https://doc.rust-lang.org/cargo/reference/features.html#dependency-features>.

       --features features
           Space or comma separated list of features to activate
           <https://doc.rust-lang.org/cargo/reference/features.html#dependency-features>. When
           adding multiple crates, the features for a specific crate may be enabled with
           package-name/feature-name syntax. This flag may be specified multiple times, which
           enables all specified features.

   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.

   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.

       -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.
