call_data: &'a [u8],

runtime_code: &'a RuntimeCode,
spawn_handle: Box<dyn CloneableSpawn + 'static>
) -> StateMachine<'a, B, H, N, Exec>
Creates new substrate state machine.
pub fn with_storage_transaction_cache(
self,
cache: Option<&'a mut StorageTransactionCache<<B as Backend<H>>::Transaction, H, N>>
) -> StateMachine<'a, B, H, N, Exec>
[src]
self,
cache: Option<&'a mut StorageTransactionCache<<B as Backend<H>>::Transaction, H, N>>
) -> StateMachine<'a, B, H, N, Exec>
Use given cache
as storage transaction cache.
The cache will be used to cache storage transactions that can be build while executing a function in the runtime. For example, when calculating the storage root a transaction is build that will be cached.
pub fn execute(
&mut self,
strategy: ExecutionStrategy
) -> Result<Vec<u8>, Box<dyn Error + 'static>>
[src]
&mut self,
strategy: ExecutionStrategy
) -> Result<Vec<u8>, Box<dyn Error + 'static>>
Execute a call using the given state backend, overlayed changes, and call executor.
On an error, no prospective changes are written to the overlay.
Note: changes to code will be in place if this call is made again. For running partial blocks (e.g. a transaction at a time), ensure a different method is used.
Returns the SCALE encoded result of the executed function.
pub fn execute_using_consensus_failure_handler<Handler, R, NC>(
&mut self,
manager: ExecutionManager<Handler>,

) -> Result<NativeOrEncoded<R>, Box<dyn Error + 'static>> where
Handler: FnOnce(Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>, Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>) -> Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>,

[src]
&mut self,
manager: ExecutionManager<Handler>,
native_call: Option<NC>
) -> Result<NativeOrEncoded<R>, Box<dyn Error + 'static>> where
Handler: FnOnce(Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>, Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>) -> Result<NativeOrEncoded<R>, <Exec as CodeExecutor>::Error>,
NC: FnOnce() -> Result<R, String> + UnwindSafe,
R: Decode + Encode + PartialEq<R>,
Execute a call using the given state backend, overlayed changes, and call executor.
On an error, no prospective changes are written to the overlay.
Note: changes to code will be in place if this call is made again. For running partial blocks (e.g. a transaction at a time), ensure a different method is used.
Returns the result of the executed function either in native representation R
or
in SCALE encoded representation.
