How to publish crate to crates.io

Publish your Rust crate to crates.io by running cargo publish after ensuring your Cargo.toml is configured correctly.

1. Verify your crate name is unique and your Cargo.toml contains valid metadata like version, authors, and license.
2. Run cargo package to simulate the publishing process and check for errors or missing files.
3. Execute cargo publish to upload your crate to the registry.

Publishing a crate is like uploading a library to a public bookshelf so other developers can find and use your code. You prepare your project by checking the details, then send it to the central Rust repository. Once uploaded, anyone can install your tool with a single command.
