fn get(&self, access_key: StorageKeyWithSpace<'_>) -> Result<Option<Box<[u8]>>>

fn set( &mut self, access_key: StorageKeyWithSpace<'_>, value: Box<[u8]> ) -> Result<()>

fn delete(&mut self, access_key: StorageKeyWithSpace<'_>) -> Result<()>

fn delete_test_only( &mut self, _access_key: StorageKeyWithSpace<'_> ) -> Result<Option<Box<[u8]>>>

fn delete_all( &mut self, access_key_prefix: StorageKeyWithSpace<'_> ) -> Result<Option<Vec<MptKeyValue>>>

fn read_all( &mut self, access_key_prefix: StorageKeyWithSpace<'_> ) -> Result<Option<Vec<MptKeyValue>>>

fn compute_state_root(&mut self) -> Result<StateRootWithAuxInfo>

It’s costly to compute state root however it’s only necessary to compute state root once before committing.

fn get_state_root(&self) -> Result<StateRootWithAuxInfo>

fn commit(&mut self, epoch_id: EpochId) -> Result<StateRootWithAuxInfo>

impl<Main: StorageStateTraitExt> StateTraitExt for ReplicatedState<Main>

fn get_with_proof( &self, access_key: StorageKeyWithSpace<'_> ) -> Result<(Option<Box<[u8]>>, StateProof)>

fn get_node_merkle_all_versions<WithProof: StaticBool>( &self, access_key: StorageKeyWithSpace<'_> ) -> Result<(NodeMerkleTriplet, NodeMerkleProof)>

Compute the merkle of the node under access_key in all tries. Node merkle is computed on the value and children hashes, ignoring the compressed path.
