Struct IOTracker 

pub struct IOTracker(/* private fields */);

Implementations

impl IOTracker

pub fn incremental_stats(&self) -> IoStats

Get IO statistics and reset the counters (incremental pattern).

This returns the accumulated statistics since the last call and resets the internal counters to zero.

pub fn stats(&self) -> IoStats

Get a snapshot of current IO statistics without resetting counters.

This returns a clone of the current statistics without modifying the internal state. Use this when you need to check stats without resetting.

pub fn record_read( &self, method: &'static str, path: Path, num_bytes: u64, range: Option<Range<u64>>, )

Record a read operation for tracking.

This is used by readers that bypass the ObjectStore layer (like LocalObjectReader) to ensure their IO operations are still tracked.

pub fn record_write(&self, method: &'static str, path: Path, num_bytes: u64)

Record a write operation for tracking.

This is used by writers that bypass the ObjectStore layer (like LocalWriter) to ensure their IO operations are still tracked.
