Struct ProcessUsage 

pub struct ProcessUsage {
    pub resident_bytes: u64,
    pub footprint_bytes: u64,
    pub cpu_seconds: f64,
    pub wakeups_total: Option<u64>,
    pub disk_ops_total: Option<u64>,
    pub disk_read_bytes: Option<u64>,
    pub disk_write_bytes: Option<u64>,
}

One snapshot of the current process’s resource usage.

Fields

resident_bytes: u64

Resident set (working set on Windows) in bytes.

footprint_bytes: u64

Private footprint in bytes: macOS phys_footprint, Windows PrivateUsage.

cpu_seconds: f64

Process CPU time (user plus system) since process start, in seconds.

wakeups_total: Option<u64>

Thread wake-ups (timer and other interrupts) since process start, when the host reports them.

disk_ops_total: Option<u64>

Disk (block or I/O) operations since process start, when the host reports them.

disk_read_bytes: Option<u64>

Bytes read from storage since process start, when the host reports them.

disk_write_bytes: Option<u64>

Bytes written to storage since process start, when the host reports them.

Implementations

impl ProcessUsage

pub fn rates_since( &self, earlier: &ProcessUsage, elapsed: Duration, ) -> UsageRates

Rates of change from earlier (an older snapshot) to self over elapsed. A zero elapsed yields zero rates rather than dividing by zero.

Trait Implementations

impl Clone for ProcessUsage

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProcessUsage

impl Debug for ProcessUsage

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

Formats the value using the given formatter.

impl Default for ProcessUsage

fn default() -> Self

Returns the “default value” for a type.
