CARGO-ADD(1)

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:

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

       o  --path path: Fetch from the specified path

       o  --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:

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

       o  Workspace members

       o  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.

OPTIONS
   Source options
       --git url
           Git URL to add the specified crate from
           <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

   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>.

           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>.

           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:

           o  auto (default): Automatically detect if color support is
              available on the terminal.

           o  always: Always display colors.

           o  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
           Overrides a Cargo configuration value.

       -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
       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.

EXAMPLES
       1. Add regex as a dependency

              cargo add regex

       2. Add trybuild as a dev-dependency

              cargo add --dev trybuild

       3. Add an older version of nom as a dependency

              cargo add nom@5

       4. Add support for serializing data structures to json with derives
