Options for OffchainWorkers
Fields§
§runtime_api_provider: Arc<RA>
Provides access to the runtime api.
keystore: Option<KeystorePtr>
Provides access to the keystore.
offchain_db: Option<Storage>
Provides access to the offchain database.
Use NoOffchainStorage
as type when passing None
to have some type that works.
transaction_pool: Option<OffchainTransactionPoolFactory<Block>>
Provides access to the transaction pool.
network_provider: Arc<dyn NetworkProvider + Send + Sync>
Provides access to network information.
is_validator: bool
Is the node running as validator?
enable_http_requests: bool
Enable http requests from offchain workers?
If not enabled, any http request will panic.
custom_extensions: CE
Callback to create custom Extension
s that should be registered for the
offchain_worker
runtime call.
These Extension
s are registered along-side the default extensions and are accessible in
the host functions.
Example:
custom_extensions: |block_hash| {
vec![MyCustomExtension::new()]
}
