pub struct CachedStateProvider<S, const PREWARM: bool = false> { /* private fields */ }Expand description
A wrapper of a state provider and a shared cache.
The const generic PREWARM controls whether every cache miss is populated. This is only
relevant for pre-warm transaction execution with the intention to pre-populate the cache with
data for regular block execution. During regular block execution the cache doesn’t need to be
populated because the actual EVM database State also caches
internally during block execution and the cache is then updated after the block with the entire
[BundleState] output of that block which contains all accessed accounts, code, storage. See
also ExecutionCache::insert_state.
