Function should_reconcile 

pub fn should_reconcile(
    current_generation: Option<i64>,
    observed_generation: Option<i64>,
) -> bool

Check if a resource’s spec has changed by comparing generation with observed_generation.

This is the standard Kubernetes pattern for determining if reconciliation is needed. The metadata.generation field is incremented by Kubernetes only when the spec changes, while status.observed_generation is set by the controller after processing a spec.

Arguments

• current_generation - The resource’s current metadata.generation
• observed_generation - The controller’s last status.observed_generation

Returns

• true - Reconciliation is needed (spec changed or first reconciliation)
• false - No reconciliation needed (spec unchanged, status-only update)

Example

use bindy::reconcilers::should_reconcile;

fn check_if_reconcile_needed(resource: &MyResource) -> bool {
    let current = resource.metadata.generation;
    let observed = resource.status.as_ref()
        .and_then(|s| s.observed_generation);

    should_reconcile(current, observed)
}

Kubernetes Generation Semantics

• metadata.generation: Incremented by Kubernetes API server when spec changes
• status.observed_generation: Set by controller to match metadata.generation after reconciliation
• When they match: spec hasn’t changed since last reconciliation → skip work
• When they differ: spec has changed → reconcile
• When observed_generation is None: first reconciliation → reconcile
