Trait MerkleRootStorage

pub trait MerkleRootStorage<Key, StorageType>: StorageInspect<StorageType>
where
    StorageType: Mappable,
{
    // Required method
    fn root(&self, key: &Key) -> Result<[u8; 32], Self::Error>;
}

Returns the merkle root for the StorageType per merkle Key. Per one storage, it is possible to have several merkle trees under different Key.

Required Methods

fn root(&self, key: &Key) -> Result<[u8; 32], Self::Error>

Return the merkle root of the stored Type in the storage.

The cryptographic primitive is an arbitrary choice of the implementor and this trait won’t impose any restrictions to that.
