Trait polkadot_sdk_frame::traits::dynamic_params::ParameterStore

pub trait ParameterStore<KV>
where
    KV: AggregatedKeyValue,
{
    // Required method
    fn get<K>(key: K) -> Option<<K as Key>::Value>
       where K: Key + Into<<KV as AggregatedKeyValue>::Key>,
             <KV as AggregatedKeyValue>::Value: TryInto<<K as Key>::WrappedValue>;
}

A dynamic parameter store across a concrete KV type.

Required Methods

fn get<K>(key: K) -> Option<<K as Key>::Value>

where K: Key + Into<<KV as AggregatedKeyValue>::Key>, <KV as AggregatedKeyValue>::Value: TryInto<<K as Key>::WrappedValue>,

Get the value of a parametrized key.
