Usage statistics for state backend.

Fields

reads: UsageUnit

Read statistics (total).

writes: UsageUnit

Write statistics (total).

nodes_writes: UsageUnit

Write trie nodes statistics.

overlay_writes: UsageUnit

Write into cached state machine change overlay.

removed_nodes: UsageUnit

Removed trie nodes statistics.

cache_reads: UsageUnit

Cache read statistics.

modified_reads: UsageUnit

Modified value read statistics.

memory: usize

Memory used.

started: Instant

Moment at which current statistics has been started being collected.

span: Duration

Timespan of the statistics.

Implementations

Empty statistics.

Means no data was collected.
