cargo-add: Add an optional dependency, which then gets exposed as a feature of the crate.
$ cargo add ${dependency} --optional
try on your machine

This command is used in cargo to add a dependency to a Rust project. Here is an explanation of each part:

  • cargo: This is the command-line tool for managing Rust projects and their dependencies.

  • add: This is a subcommand of the cargo tool used for adding dependencies to a project.

  • ${dependency}: This is a placeholder for the specific name of the dependency you want to add. You need to replace ${dependency} with the actual name of the dependency you want to install.

  • --optional: This is an optional flag that can be added to the command. When used, it marks the dependency as optional. This means that the dependency is not required for the project to build or run. Optional dependencies are typically used when you want to provide additional functionality or support for certain features in your project, but they are not essential for the core functionality.

By running cargo add ${dependency} --optional with your desired ${dependency} name, Cargo will automatically download and add the specified dependency to your project. If the --optional flag is included, the dependency will be marked as optional in your project's configuration files (such as Cargo.toml).

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
