Trait fuel_core_storage::MerkleRootStorage

pub trait MerkleRootStorage<Key, StorageType>: StorageMutate<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. The type should implement the StorageMutate for the StorageType. 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.
