Struct sc_client_api::execution_extensions::ExecutionExtensions [−][src]
pub struct ExecutionExtensions<Block: Block> { /* fields omitted */ }
Expand description
A producer of execution extensions for offchain calls.
This crate aggregates extensions available for the offchain calls
and is responsible for producing a correct Extensions object.
for each call, based on required Capabilities.
Implementations
pub fn new(
strategies: ExecutionStrategies,
keystore: Option<SyncCryptoStorePtr>,
offchain_db: Option<Box<dyn DbExternalitiesFactory>>
) -> Self
pub fn new(
strategies: ExecutionStrategies,
keystore: Option<SyncCryptoStorePtr>,
offchain_db: Option<Box<dyn DbExternalitiesFactory>>
) -> SelfCreate new ExecutionExtensions given a keystore and ExecutionStrategies.
Get a reference to the execution strategies.
Set the new extensions_factory
pub fn register_transaction_pool<T>(&self, pool: &Arc<T>) where
T: OffchainSubmitTransaction<Block> + 'static,
pub fn register_transaction_pool<T>(&self, pool: &Arc<T>) where
T: OffchainSubmitTransaction<Block> + 'static, Register transaction pool extension.
Based on the execution context and capabilities it produces the extensions object to support desired set of APIs.
pub fn manager_and_extensions<E: Debug, R: Codec>(
&self,
at: &BlockId<Block>,
context: ExecutionContext
) -> (ExecutionManager<DefaultHandler<R, E>>, Extensions)
pub fn manager_and_extensions<E: Debug, R: Codec>(
&self,
at: &BlockId<Block>,
context: ExecutionContext
) -> (ExecutionManager<DefaultHandler<R, E>>, Extensions)Create ExecutionManager and Extensions for given offchain call.
Based on the execution context and capabilities it produces the right manager and extensions object to support desired set of APIs.
