[][src]Struct sc_client::StateMachine

pub struct StateMachine<'a, B, H, N, Exec> where
    B: Backend<H>,
    H: Hasher,
    N: BlockNumber
{ /* fields omitted */ }

The substrate state machine.

Methods

impl<'a, B, H, N, Exec> StateMachine<'a, B, H, N, Exec> where
    B: Backend<H>,
    Exec: CodeExecutor + Clone + 'static,
    H: Hasher,
    N: BlockNumber,
    <H as Hasher>::Out: Ord,
    <H as Hasher>::Out: 'static,
    <H as Hasher>::Out: Codec
[src]

pub fn new(
    backend: &'a B,
    changes_trie_state: Option<State<'a, H, N>>,
    overlay: &'a mut OverlayedChanges,
    exec: &'a Exec,
    method: &'a str,
    call_data: &'a [u8],
    extensions: Extensions,
    runtime_code: &'a RuntimeCode,
    spawn_handle: Box<dyn CloneableSpawn + 'static>
) -> StateMachine<'a, B, H, N, Exec>
[src]

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]

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]

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>,
    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>, 
[src]

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.
