Module ManageRole 

Manage Role

File: IPC/Permission/Role/ManageRole.rs

Role in Mountain Architecture

Defines and manages role structures for role-based access control (RBAC), providing organizational hierarchy for user permissions across the system.

Primary Responsibility

Define role and permission structures for RBAC system with inheritance support.

Secondary Responsibilities

• Create role definitions with assigned permissions
• Create permission definitions with categorization
• Support role hierarchy and permission inheritance
• Validate role and permission integrity

Dependencies

External Crates:

• serde - Serialization for storage and transport
• std::collections::HashSet - Unique permission tracking

Internal Modules:

• Validate::{SecurityContext} - Security context validation
• LogEvent::{SecurityEvent} - Security event logging

Dependents

• Validate - Uses roles for permission validation
• TauriIPCServer - Manages roles for IPC authorization

VSCode Pattern Reference

Matches VSCode’s role system in vs/platform/permissions/common/permissions.ts

• Hierarchical role definitions
• Permission categorization
• Role inheritance support
• Permission uniqueness validation

Security Considerations

• Role names are case-sensitive for precise control
• Permission names follow hierarchical naming (category.action)
• Role inheritance prevents permission escalation through ambiguity
• Role modifications logged for audit trails
• Default roles cannot be deleted without confirmation
• Permission deduplication prevents duplicate permissions in roles

Performance Considerations

• HashSet for unique permissions enables O(1) lookup
• Role hierarchy flattened for fast permission resolution
• Lazy initialization of role collections
• Minimal copying of permission data

Error Handling Strategy

• Returns Result for explicit error handling
• Duplicate permissions ignored with warning
• Invalid role/permission names rejected early
• Circular dependency detection in role hierarchy

Thread Safety

• Immutable role definitions after creation
• Clone semantics for safe sharing across threads

TODO Items

• Implement role hierarchy with parent/child relationships
• Add permission negation (deny permissions)
• Support role templates for common permission sets
