Statistics about buffer manager state.

Fields

budget: usize

Total memory budget in bytes.

total_allocated: usize

Returns the utilization as a percentage (0 to 100).

pub fn region_usage(&self, region: MemoryRegion) -> usize

Returns allocated bytes for a specific region.

pub fn available(&self) -> usize

Returns available bytes (budget - allocated).
