Required Methods§
sourcefn execution_extensions(&self) -> &ExecutionExtensions<B>
fn execution_extensions(&self) -> &ExecutionExtensions<B>
Returns the ExecutionExtensions
.
sourcefn call(
&self,
at_hash: <B as Block>::Hash,
method: &str,
call_data: &[u8],
context: CallContext,
) -> Result<Vec<u8>, Error>
fn call( &self, at_hash: <B as Block>::Hash, method: &str, call_data: &[u8], context: CallContext, ) -> Result<Vec<u8>, Error>
Execute a call to a contract on top of state in a block of given hash.
No changes are made.
sourcefn contextual_call(
&self,
at_hash: <B as Block>::Hash,
method: &str,
call_data: &[u8],
changes: &RefCell<OverlayedChanges<<<B as Block>::Header as Header>::Hashing>>,
proof_recorder: &Option<Recorder<<<B as Block>::Header as Header>::Hashing>>,
call_context: CallContext,
extensions: &RefCell<Extensions>,
) -> Result<Vec<u8>, Error>
fn contextual_call( &self, at_hash: <B as Block>::Hash, method: &str, call_data: &[u8], changes: &RefCell<OverlayedChanges<<<B as Block>::Header as Header>::Hashing>>, proof_recorder: &Option<Recorder<<<B as Block>::Header as Header>::Hashing>>, call_context: CallContext, extensions: &RefCell<Extensions>, ) -> Result<Vec<u8>, Error>
Execute a contextual call on top of state in a block of a given hash.
No changes are made. Before executing the method, passed header is installed as the current header of the execution context.
sourcefn runtime_version(
&self,
at_hash: <B as Block>::Hash,
) -> Result<RuntimeVersion, Error>
fn runtime_version( &self, at_hash: <B as Block>::Hash, ) -> Result<RuntimeVersion, Error>
Extract RuntimeVersion of given block
No changes are made.
