Struct PropertyMetrics 

pub struct PropertyMetrics {
    pub total_changes: usize,
    pub observer_calls: usize,
    pub avg_notification_time: Duration,
}

Performance metrics for an observable property

This struct provides insight into property usage patterns and observer notification performance, useful for debugging and performance optimization.

Examples

use observable_property::ObservableProperty;
use std::sync::Arc;

let property = ObservableProperty::new(0);

property.subscribe(Arc::new(|old, new| {
    println!("Value changed: {} -> {}", old, new);
}))?;

property.set(42)?;
property.set(100)?;

let metrics = property.get_metrics()?;
println!("Total changes: {}", metrics.total_changes);
println!("Observer calls: {}", metrics.observer_calls);
println!("Avg notification time: {:?}", metrics.avg_notification_time);

Fields

total_changes: usize

Total number of times the property value has changed

observer_calls: usize

Total number of observer calls (notification events)

avg_notification_time: Duration

Average time taken to notify all observers per change
