Struct ResourceStats 

pub struct ResourceStats { /* private fields */ }

Statistics for an resource group.

Implementations

impl ResourceStats

pub fn has_allocated(&self) -> bool

Returns true if the given group has allocated any memory at all.

pub fn snapshot_delta( &self, previous: &ResourceStatsSnapshot, ) -> ResourceStatsSnapshot

Captures a snapshot of the current statistics based on the delta from a previous snapshot.

This can be used to keep a single local snapshot of the last delta, and then both track the delta since that snapshot, as well as update the snapshot to the current statistics.

Callers should generally create their snapshot via ResourceStatsSnapshot::empty and then use this method to get their snapshot delta, utilize those delta values in whatever way is necessary, and then merge the snapshot delta into the primary snapshot via ResourceStatsSnapshot::merge to make it current.
