Struct SystemStats 

pub struct SystemStats {
    pub rss_bytes: u64,
    pub cpu_time: Duration,
}

Available on crate feature system-stats only.

Snapshot of process-level memory and CPU usage.

Build via SystemSampler::sample. Pair before/after samples to derive deltas during a stress run.

Fields

rss_bytes: u64

Resident set size at sample time, in bytes.

cpu_time: Duration

Cumulative CPU time used by the process at sample time.

Implementations

impl SystemStats

pub fn compare( name: &str, before: SystemStats, after: SystemStats, peak_rss_bytes_threshold: Option<u64>, ) -> CheckResult

Compare a before/after pair and emit a CheckResult.

peak_rss_bytes_threshold flags Fail+Warning when the after RSS exceeds the threshold. None disables the check.

Always carries the stress, system tags and numeric evidence for rss_bytes_before, rss_bytes_after, rss_delta_bytes, cpu_time_before_s, cpu_time_after_s, cpu_time_delta_s.

Trait Implementations

impl Clone for SystemStats

fn clone(&self) -> SystemStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemStats

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

Formats the value using the given formatter.

impl PartialEq for SystemStats

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

impl Copy for SystemStats
