Implementations

impl<'a> RollbackWrapper<'a>

pub fn new(store: &'a mut dyn ClarityBackingStore) -> RollbackWrapper<'a>

pub fn from_persisted_log( store: &'a mut dyn ClarityBackingStore, log: RollbackWrapperPersistedLog ) -> RollbackWrapper<'a>

pub fn get_cc_special_cases_handler( &self ) -> Option<&'static dyn Fn(&mut GlobalContext<'_, '_>, Option<&PrincipalData>, Option<&PrincipalData>, &QualifiedContractIdentifier, &str, &[Value], &Value) -> Result<(), Error>>

pub fn nest(&mut self)

pub fn rollback(&mut self)

pub fn depth(&self) -> usize

pub fn commit(&mut self)

impl<'a> RollbackWrapper<'a>

pub fn put(&mut self, key: &str, value: &str)

pub fn set_block_hash( &mut self, bhh: StacksBlockId, query_pending_data: bool ) -> Result<StacksBlockId, Error>

query_pending_data indicates whether the rollback wrapper should query the rollback wrapper’s pending data on reads. This is set to false during (at-block …) closures, and true otherwise.

pub fn get_with_proof<T>(&mut self, key: &str) -> Option<(T, Vec<u8>)>where T: ClarityDeserializable<T>,

this function will only return commitment proofs for values already materialized in the underlying store. otherwise it returns None.

pub fn get<T>(&mut self, key: &str) -> Option<T>where T: ClarityDeserializable<T>,

pub fn get_value( &mut self, key: &str, expected: &TypeSignature ) -> Result<Option<ValueResult>, SerializationError>

Get a Clarity value from the underlying Clarity KV store. Returns Some if found, with the Clarity Value and the serialized byte length of the value.

pub fn get_current_block_height(&mut self) -> u32

This is the height we are currently constructing. It comes from the MARF.

pub fn get_block_header_hash( &mut self, block_height: u32 ) -> Option<StacksBlockId>

Is None if block_height >= the “currently” under construction Stacks block height.

pub fn prepare_for_contract_metadata( &mut self, contract: &QualifiedContractIdentifier, content_hash: Sha512Trunc256Sum )

pub fn insert_metadata( &mut self, contract: &QualifiedContractIdentifier, key: &str, value: &str )

pub fn get_metadata( &mut self, contract: &QualifiedContractIdentifier, key: &str ) -> Result<Option<String>, Error>

pub fn get_metadata_manual( &mut self, at_height: u32, contract: &QualifiedContractIdentifier, key: &str ) -> Result<Option<String>, Error>

pub fn has_entry(&mut self, key: &str) -> bool

pub fn has_metadata_entry( &mut self, contract: &QualifiedContractIdentifier, key: &str ) -> bool
