| //! # Device Policy Engine |
| //! |
| //! This crate provides a policy engine for managing device authorization, |
| //! specifically for controlling PCI tunnels based on system state like user login |
| //! and screen lock status. |
| //! |
| //! It operates by listening to kernel Uevents in a background and |
| //! managing authorization state based on commands received through its public API. |
| //! |
| //! The primary entry point for this library is the `PolicyEngine` struct. |
| |
| /// Defines shared data structures and the primary control trait. |
| pub mod common; |
| /// Provides mode selection between alt modes. |
| pub mod mode_selector; |
| /// Implements the core authorization logic and Uevent handling. |
| pub mod pci_authorizer; |
| /// Provides the main public-facing API for the library. |
| pub mod policy_engine; |
| /// Provided sysfs utilities |
| pub mod sysfs; |
