Struct AllocStats 

pub struct AllocStats {
    pub regions_created: usize,
    pub regions_freed: usize,
    pub total_allocated: usize,
    pub total_freed: usize,
    pub peak_usage: usize,
}

Allocation statistics snapshot.

Fields

regions_created: usize

Total number of regions ever created (including recycled).

regions_freed: usize

Total number of regions freed (returned to the free list).

total_allocated: usize

Total bytes allocated across all active regions.

total_freed: usize

Total capacity freed (bytes in freed regions).

peak_usage: usize

Peak in-use byte count observed.

Implementations

impl AllocStats

pub fn active_regions(&self) -> usize

Net active regions (created minus freed).

pub fn utilization(&self, total_capacity: usize) -> f64

Efficiency ratio: bytes allocated vs total capacity allocated so far.

Trait Implementations

impl Clone for AllocStats

fn clone(&self) -> AllocStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocStats

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

Formats the value using the given formatter.

impl Default for AllocStats

fn default() -> AllocStats

Returns the “default value” for a type.

impl Display for AllocStats

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

Formats the value using the given formatter.

impl PartialEq for AllocStats

fn eq(&self, other: &AllocStats) -> 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.
