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.

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.
