regent-sdk 0.9.1

//! Service management attribute
//!
//! This module provides the `ServiceBlockExpectedState` type for managing system services.
//!
//! **Compatible OS:**
//! - Linux (all distributions with systemd) - uses `systemctl`
//! - Windows (when `windows` feature is enabled) - uses `sc.exe` and `net` commands
//!
//! # Examples
//!
//! ## Rust API
//!
//! ```no_run
//! use regent_sdk::state::attribute::system::service::{ServiceBlockExpectedState, ServiceExpectedState, ServiceAction};
//! use regent_sdk::{Attribute, ExpectedState, Privilege};
//!
//! // Ensure httpd service is running and enabled
//! let httpd = ServiceBlockExpectedState::state(
//!     "httpd",
//!     ServiceExpectedState::Started,
//!     true
//! );
//!
//! // Just manage service state (running/stopped)
//! let nginx = ServiceBlockExpectedState::state("nginx", ServiceExpectedState::Started, false);
//!
//! // Just manage whether service is enabled at boot
//! let mysql = ServiceBlockExpectedState::enabled("mysql", true);
//!
//! // Manage unconditional action (restart)
//! let redis = ServiceBlockExpectedState::restarted("redis");
//!
//! let expected_state = ExpectedState::new()
//!     .with_attribute(Attribute::service(httpd, Privilege::WithSudo, None))
//!     .build();
//! ```
//!
//! ## YAML API
//!
//! ```yaml
//! Attributes:
//!   - Name: Httpd must be running and enabled
//!     Privilege: !WithSudo
//!     Detail: !Service
//!       Name: httpd
//!       State: Started
//!       Enabled: true
//! ```
//!
//! For state-only configuration:
//!
//! ```yaml
//! Attributes:
//!   - Name: Nginx must be stopped
//!     Privilege: !WithSudo
//!     Detail: !Service
//!       Name: nginx
//!       State: Stopped
//! ```
//!
//! For enabled-only configuration:
//!
//! ```yaml
//! Attributes:
//!   - Name: MySQL must be disabled at boot
//!     Privilege: !WithSudo
//!     Detail: !Service
//!       Name: mysql
//!       Enabled: false
//! ```
