Struct QueryTimestamp 

pub struct QueryTimestamp(/* private fields */);

Available on crate feature core only.

A timestamp for query operations, in milliseconds since UNIX epoch.

Used for cache freshness checks (TTL, stale-while-revalidate) and for recording when data was last updated. Obtain the current time via QueryTimestamp::from_millis(...) using your application’s clock.

Implementations

impl QueryTimestamp

pub fn from_millis(value: u64) -> Self
