Error Handling

// Librerías: thiserror
#[derive(Debug, thiserror::Error)]
enum AppError {
    #[error("not found: {0}")]
    NotFound(String),
    #[error("database error")]
    Database(#[from] sqlx::Error),
}

// Aplicaciones: anyhow
fn main() -> anyhow::Result<()> {
    let config = load_config().context("failed to load config")?;
    Ok(())
}
