Crate duende_core 

duende-core

Core daemon lifecycle primitives for the Duende cross-platform daemon framework.

This crate provides the foundational types and traits for daemon management:

• Daemon trait for implementing daemon lifecycle
• DaemonConfig for daemon configuration
• DaemonMetrics for RED method metrics (Rate, Errors, Duration)
• DaemonContext for runtime context and signal handling

Iron Lotus Framework

This crate follows the Iron Lotus Framework principles:

• Genchi Genbutsu: All operations traceable to syscalls via renacer
• Jidoka: Explicit error handling, no panics
• Kaizen: Continuous metrics for improvement
• Muda: Zero-waste resource allocation

Example

use duende_core::{Daemon, DaemonConfig, DaemonContext, DaemonId, ExitReason};
use async_trait::async_trait;

struct MyDaemon {
    id: DaemonId,
}

#[async_trait]
impl Daemon for MyDaemon {
    fn id(&self) -> DaemonId { self.id }
    fn name(&self) -> &str { "my-daemon" }
    // ... implement other methods
}
