Trait frame_support::traits::dynamic_params::ParameterStore

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

A dynamic parameter store across a concrete KV type.

Required Methods

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

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

Get the value of a parametrized key.

Object Safety

This trait is not object safe.
