CARGO-ADD(1) General Commands Manual 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:
• 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.
