Key Changes Required
- Batch Data Structures - Create batch request structures in
common_types/src/types.rsfor different operation types - Batch Token Operations - Add batch functions to
membership_token.rswith proper validation and size limits - Batch Attendance Logging - Implement batch attendance operations in
attendance_log.rswith optimized storage patterns - Batch Role Management - Add batch role operations to
access_control.rswith proper authorization checks - Gas Optimization - Implement batch size limits and gas estimation functions to prevent transaction failures
- Partial Success Handling - Design the batch operations to handle scenarios where some operations succeed and others fail
- Batch Events - Emit appropriate events for batch operations including success/failure counts
Acceptance Criteria
- Add batch_issue_tokens function with max 50 tokens per batch
- Add batch_log_attendance function with max 100 entries per batch
- Add batch_set_roles function with max 25 roles per batch
- Implement proper validation for batch operations
- Add gas estimation functions for batch operations
- Include comprehensive batch operation tests
- Add partial success handling (some operations succeed, others fail)
- Implement batch operation events and logging
