impl<'backend, 'config, B: Clone> Clone for MemoryStackState<'backend, 'config, B>

fn clone(&self) -> MemoryStackState<'backend, 'config, B>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

fn is_authority_cold(&mut self, address: H160) -> Option<bool>

EIP-7702 - check is authority cold.

fn get_authority_target(&mut self, authority: H160) -> Option<H160>

Get authority target (EIP-7702) - delegated address. First we’re trying to get authority target from the cache recursively with parent state, if it’s not found we get code for the authority address and check if it’s delegation designator. If it’s true, we add result to cache and return delegated target address.
