Affects backend::AsTrieBackend, backend::BackendRuntimeCode, ext::Error, sp-state-machine::DefaultError, overlayed_changes::StorageChanges.transaction_index_changes, overlayed_changes::OverlayedExtension, overlayed_changes::OverlayedExtensions, stats::UsageInfo.started, stats::UsageInfo.span, trie_backend::create_proof_check_backend…
