Struct sc_service::LocalCallExecutor

pub struct LocalCallExecutor<Block: BlockT, B, E> { /* private fields */ }

Call executor that executes methods locally, querying all required data from local backend.

Implementations

impl<Block: BlockT, B, E> LocalCallExecutor<Block, B, E>

where E: CodeExecutor + RuntimeVersionOf + Clone + 'static, B: Backend<Block>,

pub fn new( backend: Arc<B>, executor: E, client_config: ClientConfig<Block>, execution_extensions: ExecutionExtensions<Block>, ) -> Result<Self>

Creates new instance of local call executor.
