Crate xtstate 

XTState

XTState is a flexible, thread-safe state management utility for tracking named boolean slots and their activation history in Rust.

Features

• Track multiple named boolean slots (flags) and their states.
• Record a timestamped history of all slot changes.
• Determine when all slots are active (true) via the activated field.
• Thread-safe usage via the ThreadSafeXTState type alias (Arc<Mutex<XTState>>).

Example Usage

use xtstate::{XTState, ThreadSafeXTState};
use std::collections::HashSet;
use std::sync::{Arc, Mutex};

// Create a new XTState
let mut xt = XTState::new();
xt.setup_slots(HashSet::from(["slot1".to_string(), "slot2".to_string()]), false);
xt.update_callback("slot1".to_string(), true);
xt.update_callback("slot2".to_string(), true);
assert!(xt.activated);

// Thread-safe usage
let state: ThreadSafeXTState = Arc::new(Mutex::new(XTState::new()));
{
    let mut xt = state.lock().unwrap();
    xt.setup_slots(HashSet::from(["slot1".to_string(), "slot2".to_string()]), false);
}
// ... spawn threads and update slots ...

Use Cases

• Feature flag management
• Workflow or step completion tracking
• Distributed system readiness coordination
• Event synchronization

Crate Features

• Requires the chrono crate for timestamping history entries.

Thread Safety

Use the ThreadSafeXTState type alias for safe sharing and mutation across threads.
