Enable TLS in Rust by adding the rustls-tls feature to reqwest in Cargo.toml.
Use the rustls-tls feature flag in your Cargo.toml to enable TLS/SSL with the reqwest crate, as shown in the trpl package configuration.
[dependencies]
reqwest = { version = "0.12", default-features = false, features = ["rustls-tls"] }
This configuration switches the underlying TLS implementation to rustls, a pure Rust TLS library, avoiding the need for external OpenSSL bindings.
Using TLS/SSL in Rust with the rustls library tells your project to handle secure internet connections safely. It matters because it ensures your code works consistently across different operating systems without needing to install extra system tools. Think of it like choosing a universal adapter for your charger so it works anywhere you travel.
