auth-framework 0.4.2

//! Comprehensive administration module for AuthFramework management.
//!
//! This module provides multiple administrative interfaces for monitoring,
//! configuring, and managing AuthFramework deployments. It includes both
//! interactive and programmatic interfaces suitable for different operational
//! environments.
//!
//! # Administrative Interfaces
//!
//! - **CLI (Command Line Interface)**: Scriptable command-line administration
//! - **TUI (Terminal User Interface)**: Interactive terminal dashboard
//! - **Web Interface**: Browser-based administrative console
//! - **API**: RESTful API for programmatic management
//!
//! # Core Capabilities
//!
//! - **Real-time Monitoring**: Live metrics and health status
//! - **Configuration Management**: Dynamic configuration updates
//! - **User Management**: User account and permission administration
//! - **Security Monitoring**: Threat detection and incident response
//! - **Audit Logging**: Comprehensive activity tracking
//! - **Performance Analytics**: System performance and optimization
//!
//! # Security Features
//!
//! - **Role-based Access**: Admin, operator, and read-only roles
//! - **Audit Trail**: All administrative actions are logged
//! - **Secure Sessions**: Encrypted admin sessions
//! - **MFA Enforcement**: Multi-factor authentication for admins
//! - **IP Whitelisting**: Restrict admin access by network
//!
//! # Monitoring Dashboard
//!
//! The administrative interfaces provide comprehensive monitoring:
//! - Active user sessions
//! - Authentication success/failure rates
//! - Security alerts and incidents
//! - System performance metrics
//! - Error rates and debugging information
//!
//! # Configuration Management
//!
//! - **Live Updates**: Modify configuration without restarts
//! - **Validation**: Real-time configuration validation
//! - **Backup/Restore**: Configuration versioning and rollback
//! - **Environment Management**: Dev, staging, production configs
//!
//! # Example Usage
//!
//! ```rust
//! use auth_framework::admin::{AdminInterface, AppState};
//!
//! // Create administrative interface
//! let app_state = AppState::new(config_manager).await?;
//! let admin = AdminInterface::new(app_state);
//!
//! // Start web interface
//! admin.start_web_interface("127.0.0.1:8080").await?;
//!
//! // Start TUI interface
//! admin.start_tui_interface().await?;
//! ```
//!
//! # Deployment Scenarios
//!
//! - **Development**: TUI for local development and testing
//! - **Production**: Web interface for remote administration
//! - **Automation**: CLI for scripted operations and CI/CD
//! - **Monitoring**: API integration with external monitoring systems
//!
//! # Integration
//!
//! Integrates with external systems:
//! - Prometheus metrics export
//! - Grafana dashboard templates
//! - SIEM system integration
//! - Log aggregation systems
