Feat: Round Instance Validation Implementation #128
Description
Overview
Implement comprehensive validation for Round instances. This issue covers the is_valid() method that ensures round instances maintain data integrity and business rule compliance.
Requirements
Function to Implement
is_valid() - Comprehensive Round Instance Validation
fn is_valid(self: @Round) -> bool- Validate all fields of an existing Round instance
- Check business rule compliance
- Verify data consistency and integrity
- Validate state transition logic
- Return true only if round is completely valid
Validation Categories
Basic Field Validation
- Round ID: Must be > 0 (no zero IDs allowed)
- Creator Address: Must be non-zero valid address
- Player Counts: players_count must be > 0 and ≤ max_players
- Ready Count: ready_players_count must be ≤ players_count
- Configuration: cards_per_round and card_timeout must be > 0
Enum Integrity Validation
- Mode Conversion: Validate mode felt252 converts to valid Mode enum
- State Conversion: Validate state felt252 converts to valid RoundState enum
- Challenge Type: Validate challenge_type felt252 converts to valid enum
- Non-Zero Validation: Converted enums must not be zero values
State Transition Validation
- Started State: If Started, start_time must be > 0
- Completed State: If Completed, both start_time and end_time must be > 0
- Time Logic: If Completed, end_time must be > start_time
- Pending State: No additional time constraints
Validation Strategy
- Fail Fast: Return false immediately on first invalid condition
- Comprehensive: Check all aspects of round integrity
- Safe: Handle all edge cases gracefully
Acceptance Criteria
-
is_valid()method implemented with comprehensive validation - All basic field validations working correctly
- Enum integrity validation complete
- State transition validation accurate
- Complete test coverage for all validation scenarios
- All edge cases and boundary conditions tested
Dependencies
- Use existing Round struct and helper methods (
get_mode(),get_state(),get_challenge_type()) - Use
Zerotrait for enum zero-value detection - No dependencies on other implementation issues
