Struct sc_client_api::execution_extensions::ExecutionExtensions

impl<Block: BlockT> ExecutionExtensions<Block>

pub fn new( strategies: ExecutionStrategies, keystore: Option<SyncCryptoStorePtr>, offchain_db: Option<Box<dyn DbExternalitiesFactory>> ) -> Self

Create new ExecutionExtensions given a keystore and ExecutionStrategies.

pub fn strategies(&self) -> &ExecutionStrategies

Get a reference to the execution strategies.

pub fn set_extensions_factory( &self, maker: impl ExtensionsFactory<Block> + 'static )

Set the new extensions_factory

pub fn register_transaction_pool<T>(&self, pool: &Arc<T>)where T: OffchainSubmitTransaction<Block> + 'static,

Register transaction pool extension.

pub fn extensions( &self, block_hash: Block::Hash, block_number: NumberFor<Block>, context: ExecutionContext ) -> Extensions

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>( &self, block_hash: Block::Hash, block_number: NumberFor<Block>, context: ExecutionContext ) -> (ExecutionManager<DefaultHandler<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.

impl<T> CheckedConversion for T

fn checked_from<T>(t: T) -> Option<Self>where Self: TryFrom<T>,

Convert from a value of T into an equivalent instance of Option<Self>. Read more

fn checked_into<T>(self) -> Option<T>where Self: TryInto<T>,

Consume self to return Some equivalent value of Option<T>. Read more

impl<T> Downcast for Twhere T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for Twhere T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
