duende-platform

Platform adapters for the Duende daemon framework.

Overview

Platform-specific implementations for spawning, signaling, and monitoring daemons across:

• Linux (systemd): Service units with cgroup resource control
• macOS (launchd): Property lists with keep-alive support
• Container (Docker/OCI): Container runtime integration
• pepita (MicroVM): Virtio-vsock communication
• WOS (WebAssembly OS): Process scheduling with priority levels
• Native (fallback): Direct process spawning

Usage

use duende_platform::{detect_platform, NativeAdapter, Platform, PlatformAdapter};

// Auto-detect platform
let platform = detect_platform();

// Create appropriate adapter
let adapter = NativeAdapter::new();

// Spawn daemon
let handle = adapter.spawn(my_daemon).await?;

// Signal daemon
adapter.signal(&handle, Signal::Term).await?;

Memory Locking (DT-007)

Prevents swap deadlock for daemons serving as swap devices:

use duende_platform::{lock_daemon_memory, is_memory_locked};

// Lock all current and future memory allocations
let result = lock_daemon_memory()?;
assert!(is_memory_locked());
