A dynamic parameter store across an aggregated KV type.

Required Associated Types

type AggregatedKeyValue: AggregatedKeyValue

Required Methods

fn get<KV, K>(key: K) -> Option<K::Value>

where KV: AggregatedKeyValue, K: Key + Into<<KV as AggregatedKeyValue>::Key>, <KV as AggregatedKeyValue>::Key: IntoKey<<<Self as RuntimeParameterStore>::AggregatedKeyValue as AggregatedKeyValue>::Key>, <<Self as RuntimeParameterStore>::AggregatedKeyValue as AggregatedKeyValue>::Value: TryIntoKey<<KV as AggregatedKeyValue>::Value>, <KV as AggregatedKeyValue>::Value: TryInto<K::WrappedValue>,

Get the value of a parametrized key.

Should return None if no explicit value was set instead of a default.
