Struct CachePolicy 

#[non_exhaustive]
pub struct CachePolicy {
    pub records: Duration,
    pub misses: Duration,
    pub searches: Duration,
}

How long cached answers are trusted (DESIGN §5). Past these, a provider is asked again; if it then fails, the old answer is served as stale.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

records: Duration

misses: Duration

“Not found” answers: short, since works get registered.

searches: Duration
