Struct evm_adapters::sputnik::state::ForkedState

pub struct ForkedState<'config, S> { /* fields omitted */ }

A state that branches off from the shared state and operates according to the following rules:

Reading:

• forked local state takes precedent over shared state: if the storage value is not present in the local state, it queries the shared state.

Writing:

• all memory altering operations will be applied to the local state

Implementations

impl<'config, S> ForkedState<'config, S> where
    S: StackState<'config>, 

pub fn new(
    shared_state: SharedState<S>,
    metadata: StackSubstateMetadata<'config>
) -> Self

Create a new forked state with the SharedState as root state This will initialize a new, empty substate that will hold all modifications to the shared_state, so that the shared state remains untouched.
