Function instance_status_changed 

pub fn instance_status_changed(
    current: Option<&Bind9InstanceStatus>,
    conditions: &[Condition],
    cluster_ref: Option<&ClusterReference>,
    zones: &[ZoneReference],
    generation: Option<i64>,
    observed_parent_generation: Option<i64>,
) -> bool

Determines whether the Bind9Instance status patch is needed.

Compares the current status against the values about to be written. The patch is needed if any of the following changed:

• cluster_ref or the zones list
• observed_generation (so spec edits that don’t change conditions still advance observedGeneration and stop perpetual re-reconciliation)
• observed_parent_generation (so parent cluster config changes are recorded once applied)
• Any condition’s type, status, reason, or message

Arguments

• current - The status currently stored on the resource (if any)
• conditions - New conditions about to be written
• cluster_ref - New cluster reference about to be written
• zones - Zones list about to be written (preserved from current status)
• generation - The metadata.generation about to be written as observed_generation
• observed_parent_generation - The parent cluster generation about to be written

Returns

true if the status patch should be applied, false if it can be skipped.
