Enable rustls in Rust by adding the rustls-tls feature to your reqwest dependency in Cargo.toml.
Enable rustls by adding the rustls-tls feature to your reqwest dependency in Cargo.toml.

reqwest = { version = "0.12", default-features = false, features = ["rustls-tls"] }
This configuration switches the TLS backend from the default OpenSSL to rustls, a pure Rust implementation, as demonstrated in the trpl crate.
Using the rustls crate in Rust TLS tells your project to use rustls for secure internet connections instead of the default option. It matters because rustls is written entirely in Rust, making it faster and easier to maintain without external dependencies. Think of it as choosing a specific, high-performance engine for your car rather than the standard one.
