How to get Cargo package metadata (version, name, description) in a Rust program?

Hi everyone! I'm writing a CLI utility in Rust and I want it to display the program version when run with the `--version` flag. But I don't want to hardcode the string "0.1.0" in the code — that's inconvenient, the version should only be changed in `Cargo.toml`. Problem: I can't figure out how to read data from `Cargo.toml` from within the Rust program itself. I tried using `std::fs::read_to_string("Cargo.toml")`, but this only works if the program is run from the project root, and after installation via `cargo install`, the `Cargo.toml` file is not located next to the binary. Here's my current code, which of course doesn't work as intended: ```rust fn main() { let version = std::fs::read_to_string("Cargo.toml") .ok() .and_then(|s| { s.lines() .find(|l| l.starts_with("version")) ```
