bon

Uses the typestate pattern to enforce required parameters and prevent duplicate setters, eliminating runtime panics as emphasized in the README.

Converts positional function parameters into named arguments with the #[builder] attribute, improving readability and enabling partial application, as shown in the greet function example.

Works seamlessly with async, fallible, generic functions, and impl Trait, making it versatile for complex Rust code, as noted in the overview.

Ensures all errors are caught at compile time, preventing runtime failures, which is a core philosophy highlighted in the README.

Provides a comprehensive guide book and API reference with detailed examples, as linked in the README for easy navigation.
