validation.rs

1//! Validation system for parsed OpenSCENARIO content
2//!
3//! This module provides comprehensive validation of OpenSCENARIO documents beyond basic XML
4//! parsing, ensuring logical consistency and adherence to domain-specific constraints.
5//!
6//! # Features
7//!
8//! - **Multi-level validation** - structure, references, constraints, and semantics
9//! - **Detailed error reporting** with location context and fix suggestions
10//! - **Performance metrics** and caching for large scenario validation
11//! - **Configurable validation** modes (strict, lenient, custom rules)
12//! - **Cross-reference checking** for entities, catalogs, and parameters
13//!
14//! # Basic Usage
15//!
16//! ## Simple Validation
17//!
18//! ```rust,no_run
19//! use openscenario_rs::parser::validation::ScenarioValidator;
20//! use openscenario_rs::parser::xml::parse_from_file;
21//!
22//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
23//! // Parse and validate a scenario
24//! let scenario = parse_from_file("scenario.xosc")?;
25//! let mut validator = ScenarioValidator::new();
26//! let result = validator.validate_scenario(&scenario);
27//!
28//! if result.is_valid() {
29//!     println!("✓ Scenario is valid");
30//! } else {
31//!     println!("✗ Found {} errors:", result.errors.len());
32//!     for error in &result.errors {
33//!         println!("  - {}: {}", error.location, error.message);
34//!         if let Some(suggestion) = &error.suggestion {
35//!             println!("    Suggestion: {}", suggestion);
36//!         }
37//!     }
38//! }
39//!
40//! // Check warnings too
41//! if !result.warnings.is_empty() {
42//!     println!("⚠ {} warnings found", result.warnings.len());
43//!     for warning in &result.warnings {
44//!         println!("  - {}: {}", warning.location, warning.message);
45//!     }
46//! }
47//! # Ok(())
48//! # }
49//! ```
50//!
51//! ## Custom Validation Configuration
52//!
53//! ```rust,no_run
54//! use openscenario_rs::parser::validation::{ScenarioValidator, ValidationConfig};
55//! use openscenario_rs::parse_from_file;
56//!
57//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
58//! # let scenario = parse_from_file("scenario.xosc")?;
59//! let config = ValidationConfig {
60//!     strict_mode: true,           // Treat warnings as errors
61//!     validate_references: true,   // Check entity/catalog references
62//!     validate_constraints: true,  // Check business rules
63//!     validate_semantics: true,    // Check logical consistency
64//!     max_errors: 50,             // Stop after 50 errors
65//!     use_cache: true,            // Enable performance caching
66//! };
67//!
68//! let mut validator = ScenarioValidator::with_config(config);
69//! let result = validator.validate_scenario(&scenario);
70//!
71//! println!("Validation completed in {}ms", result.metrics.duration_ms);
72//! println!("Validated {} elements", result.metrics.elements_validated);
73//! # Ok(())
74//! # }
75//! ```
76//!
77//! ## Validation Categories
78//!
79//! The validator checks multiple categories of issues:
80//!
81//! ### Structural Validation
82//! - Required fields and attributes
83//! - Valid data types and ranges
84//! - Schema compliance
85//!
86//! ### Reference Validation
87//! ```rust
88//! // Checks that entity references point to defined entities
89//! // Validates catalog references exist and are accessible
90//! // Ensures parameter references resolve correctly
91//! ```
92//!
93//! ### Constraint Validation
94//! ```rust
95//! // Enforces OpenSCENARIO business rules
96//! // Checks unique names and IDs
97//! // Validates value ranges and relationships
98//! ```
99//!
100//! ### Semantic Validation
101//! ```rust
102//! // Ensures logical consistency
103//! // Detects impossible scenarios
104//! // Validates temporal relationships
105//! ```
106//!
107//! # Error Categories and Handling
108//!
109//! ```rust
110//! use openscenario_rs::parser::validation::ValidationErrorCategory;
111//!
112//! # let result = openscenario_rs::parser::validation::ValidationResult::new();
113//! for error in &result.errors {
114//!     match error.category {
115//!         ValidationErrorCategory::MissingRequired => {
116//!             // Handle missing required fields
117//!             eprintln!("Missing required field: {}", error.location);
118//!         }
119//!         ValidationErrorCategory::InvalidReference => {
120//!             // Handle broken references
121//!             eprintln!("Invalid reference at {}: {}", error.location, error.message);
122//!         }
123//!         ValidationErrorCategory::ConstraintViolation => {
124//!             // Handle business rule violations
125//!             eprintln!("Constraint violation: {}", error.message);
126//!         }
127//!         ValidationErrorCategory::SemanticError => {
128//!             // Handle logical inconsistencies
129//!             eprintln!("Semantic error: {}", error.message);
130//!         }
131//!         ValidationErrorCategory::TypeMismatch => {
132//!             // Handle type errors
133//!             eprintln!("Type mismatch: {}", error.message);
134//!         }
135//!         ValidationErrorCategory::ParameterError => {
136//!             // Handle parameter resolution errors
137//!             eprintln!("Parameter error: {}", error.message);
138//!         }
139//!     }
140//! }
141//! ```
142//!
143//! # Performance Optimization
144//!
145//! For large scenarios or repeated validations:
146//!
147//! ```rust,no_run
148//! use openscenario_rs::parser::validation::{ScenarioValidator, ValidationConfig};
149//! use openscenario_rs::parser::xml::parse_from_file;
150//!
151//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
152//! # let scenario_files = vec!["scenario1.xosc", "scenario2.xosc"];
153//! let config = ValidationConfig {
154//!     use_cache: true,         // Enable validation caching
155//!     max_errors: 20,          // Stop early to save time
156//!     validate_semantics: false, // Skip expensive semantic checks
157//!     ..Default::default()
158//! };
159//!
160//! let mut validator = ScenarioValidator::with_config(config);
161//!
162//! // Validate multiple scenarios efficiently
163//! for scenario_file in scenario_files {
164//!     let scenario = parse_from_file(scenario_file)?;
165//!     let result = validator.validate_scenario(&scenario);
166//!
167//!     println!("Cache hit ratio: {:.1}%", result.metrics.cache_hit_ratio * 100.0);
168//! }
169//! # Ok(())
170//! # }
171//! ```
172//!
173//! # Integration with Parsing
174//!
175//! ```rust,no_run
176//! use openscenario_rs::parser::{xml, validation};
177//!
178//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
179//! // Parse and validate in one step
180//! let scenario = xml::parse_from_file_validated("scenario.xosc")?;
181//!
182//! // Then do domain-specific validation
183//! let mut validator = validation::ScenarioValidator::new();
184//! let validation_result = validator.validate_scenario(&scenario);
185//!
186//! // Check both parsing and validation results
187//! if validation_result.is_clean() {
188//!     println!("Scenario is fully valid and clean");
189//! }
190//! # Ok(())
191//! # }
192//! ```
