Accumulated usage statistics specific to state machine crate.

Fields

reads_modified: RefCell<u64>

Number of read query from runtime that hit a modified value (in state machine overlay).

bytes_read_modified: RefCell<u64>

Size in byte of read queries that hit a modified value.

writes_overlay: RefCell<u64>

Number of time a write operation occurs into the state machine overlay.

bytes_writes_overlay: RefCell<u64>

Size in bytes of the writes overlay operation.
