Struct DefaultAdmissionPolicy 

Source 
pub struct DefaultAdmissionPolicy;
Expand description

Default policy: admit only Data packets that have a positive FreshnessPeriod.

Data without FreshnessPeriod or with FreshnessPeriod=0 is immediately stale and not worth caching — it would fill the CS with entries that can never satisfy MustBeFresh Interests, causing eviction churn under high throughput. This matches NFD’s default admit policy behavior.
