Struct sc_client_api::execution_extensions::ExecutionExtensions

source · 
pub struct ExecutionExtensions<Block: BlockT> { /* private fields */ }
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§

source§

impl<Block: BlockT> ExecutionExtensions<Block>

source

pub fn new( extensions_factory: Option<Box<dyn ExtensionsFactory<Block>>>, read_runtime_version: Arc<dyn ReadRuntimeVersion> ) -> Self

source

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

Set the new extensions_factory

source

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

Based on the execution context and capabilities it produces the extensions object to support desired set of APIs.
