Struct InMemoryStore

Source
pub struct InMemoryStore {
    data: RwLock<BTreeMap<(u64, u32, i64), TemporalPoint>>,
}
Expand description

Non-persistent in-memory storage using a sorted BTreeMap.

Thread-safe: multiple readers or one writer via [RwLock]. All data is lost when the process exits.

Fields§

§data: RwLock<BTreeMap<(u64, u32, i64), TemporalPoint>>
