Remove a cached value

fn cache_set_refresh(&mut self, refresh: bool) -> bool

Set the flag to control whether cache hits refresh the ttl of cached values, returns the old flag value

Provided methods

fn cache_lifespan(&self) -> Option<u64>

Return the lifespan of cached values (time to eviction)

fn cache_set_lifespan(&mut self, _seconds: u64) -> Option<u64>

Set the lifespan of cached values, returns the old value
