Struct SystemSampler 

pub struct SystemSampler { /* private fields */ }

Available on crate feature system-stats only.

Stateful sampler that refreshes process info on demand.

Allocates one sysinfo::System instance for reuse across samples.

Example (ignored: requires sysinfo + a real process)

use dev_stress::system::SystemSampler;

let mut sampler = SystemSampler::new();
let before = sampler.sample().unwrap();
// ... run workload ...
let after = sampler.sample().unwrap();
assert!(after.rss_bytes >= before.rss_bytes.saturating_sub(1024 * 1024));

Implementations

impl SystemSampler

pub fn new() -> Self

Build a new sampler bound to the current process.

pub fn sample(&mut self) -> Option<SystemStats>

Capture a SystemStats snapshot.

Returns None if the OS has no record of the process (extremely rare; would imply the current PID is unknown).

Trait Implementations

impl Default for SystemSampler

fn default() -> Self

Returns the “default value” for a type.
