openscenario-rs 0.3.1

//! Basic parsing example demonstrating simple OpenSCENARIO file loading
//!
//! This example contains:
//! - Simple scenario file loading and parsing
//! - Basic error handling and validation
//! - Accessing parsed scenario data and entities
//! - Demonstrating the high-level convenience API
//! - Basic scenario introspection and data access patterns
//!
