Struct AllocationStats 

pub struct AllocationStats {
    pub total_bytes: u64,
    pub total_blocks: u64,
    pub peak_bytes: u64,
    pub peak_blocks: u64,
}

Available on crate feature alloc-tracking only.

Snapshot of allocation activity, captured from mod_alloc::dhat_compat::HeapStats (drop-in for dhat::HeapStats).

Build via AllocationStats::snapshot inside a mod_alloc::dhat_compat::Profiler scope.

Fields

total_bytes: u64

Total bytes allocated across the profiled scope (cumulative).

total_blocks: u64

Total number of allocations across the profiled scope.

peak_bytes: u64

Peak bytes resident at any one time.

peak_blocks: u64

Peak number of blocks resident at any one time.

Implementations

impl AllocationStats

pub fn snapshot() -> Self

Capture the current HeapStats into an AllocationStats.

SHOULD be called inside an active mod_alloc::dhat_compat::Profiler::new_heap() scope so the profiler’s drop-time JSON write captures the same data. The snapshot itself works outside a Profiler scope (returns zeros if no global allocator is installed); the historical dhat-rs panic is no longer present.

pub fn compare_against_baseline( &self, name: &str, baseline: Option<AllocationStats>, pct_threshold: f64, ) -> CheckResult

Compare this snapshot against a baseline.

pct_threshold is the maximum tolerated growth in total_bytes over the baseline. A regression beyond the threshold yields Fail (Warning). No baseline yields Skip.

Trait Implementations

impl Clone for AllocationStats

fn clone(&self) -> AllocationStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AllocationStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for AllocationStats

fn eq(&self, other: &AllocationStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
