Struct InstrumentedTrieCursorFactory 

pub struct InstrumentedTrieCursorFactory<F> { /* private fields */ }

Available on crate feature metrics only.

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.

Implementations

impl<F> InstrumentedTrieCursorFactory<F>

pub const fn new( factory: F, account_metrics: TrieCursorMetrics, storage_metrics: TrieCursorMetrics, ) -> Self

Wraps a factory with account and storage metric handles shared by its cursors.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
