Struct PoolStats 

pub struct PoolStats {
    pub hit_count: u64,
    pub miss_count: u64,
    pub evict_count: u64,
    pub idle_count: usize,
    pub in_use_count: usize,
}

Available on Linux or macOS only.

Warm pool types for reusing pre-initialized OS sandboxes. Point-in-time statistics for a SandboxPool.

Counters are cumulative for the lifetime of the pool. Size fields describe the state observed when SandboxPool::stats took the snapshot.

Fields

hit_count: u64

Number of times acquire() hits the idle pool.

miss_count: u64

Number of times acquire() misses and creates a new sandbox.

evict_count: u64

Number of evictions due to timeout, failed health checks, or capacity pressure.

idle_count: usize

Current number of idle sandboxes.

in_use_count: usize

Current number of checked-out sandboxes.

Trait Implementations

impl Clone for PoolStats

fn clone(&self) -> PoolStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolStats

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

Formats the value using the given formatter.

impl Default for PoolStats

fn default() -> PoolStats

Returns the “default value” for a type.

impl PartialEq for PoolStats

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