pub struct MemoryOverlayStateProviderRef<'a> { /* private fields */ }Expand description
A state provider that stores references to in-memory blocks along with their state as well as a reference of the historical state provider for fallback lookups.

impl<'a> MemoryOverlayStateProviderRef<'a>
Sourcepub fn new(
historical: Box<dyn StateProvider + 'a>,
in_memory: Vec<ExecutedBlock>,
) -> Self
pub fn new( historical: Box<dyn StateProvider + 'a>, in_memory: Vec<ExecutedBlock>, ) -> Self
