pub struct ExecutionExtensions<Block: Block> { /* 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.
