Struct trust_dns_resolver::dns_lru::TtlConfig

pub struct TtlConfig { /* private fields */ }

The time-to-live, TTL, configuration for use by the cache.

It should be understood that the TTL in DNS is expressed with a u32. We use Duration here for tracking this which can express larger values than the DNS standard. Generally a Duration greater than u32::MAX_VALUE shouldn’t cause any issue as this will never be used in serialization, but understand that this would be outside the standard range.
