//! Error handling patterns for ghurni.
//!
//! Demonstrates how to handle errors from constructors and synthesis.
//!
//! Run: `cargo run --example error_handling`

use ghurni::prelude::*;

fn main() {
    // Pattern 1: Propagate with ?
    if let Err(e) = run_synthesis() {
        println!("Synthesis error: {e}");

    // Pattern 2: Match on variant
    match Engine::new(EngineType::Gasoline, 4, f32::NAN) {
        Err(GhurniError::InvalidParameter(msg)) => {
            println!("Invalid parameter (expected): {msg}");
        }
        Err(e) => println!("Other error: {e}"),
        Ok(_) => println!("Unexpected success with NaN sample rate"),
