InstrumentedHashedCursorFactory

reth_trie::hashed_cursor::metrics

Struct InstrumentedHashedCursorFactory 

Source 
pub struct InstrumentedHashedCursorFactory<F> { /* private fields */ }
Available on crate feature metrics only.
Expand description

Instruments every account and storage cursor opened by the wrapped factory.

Counters are owned by each cursor and recorded into the supplied handles on drop. Wrap the outermost overlay factory to include both overlay and database operations in these counters.
