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.

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

block_hash: Block::Hash,
block_number: NumberFor<Block>,
context: ExecutionContext
) -> Extensions
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.
