Trait ExtensionsFactory 

pub trait ExtensionsFactory<Block: BlockT>: Send + Sync {
    // Required method
    fn extensions_for(
        &self,
        block_hash: Block::Hash,
        block_number: NumberFor<Block>,
    ) -> Extensions;
}

Generate the starting set of Extensions.

These Extensions are passed to the environment a runtime is executed in.

Required Methods

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

Create Extensions for the given input.

• block_hash: The hash of the block in the context that extensions will be used.
• block_number: The number of the block in the context that extensions will be used.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
