🚩 Feature Flags & Toggles

Feature flags allow developers to safely roll out new features to a subset of users, perform A/B testing, or instantaneously disable failing endpoints without redeploying code.

integrations/ferrox-feature-flags provides feature flag evaluation tools.

1. Evaluating Feature Flags​

use ferrox_feature_flags::FeatureFlagEngine;

let flags = FeatureFlagEngine::new();

// Evaluate flag for a specific user ID
if flags.is_enabled("new_dashboard_v2", "user_101") {
    println!("Rendering Dashboard V2");
} else {
    println!("Rendering Legacy Dashboard V1");
}

2. Dynamic Remote Toggle Provider (Unleash / Local)​

FeatureFlagEngine supports loading flag states dynamically from environment variables, Redis, or Unleash servers.
