Struct ProcessStats 

pub struct ProcessStats {
    pub user_ms: u64,
    pub system_ms: u64,
    pub peak_rss: u64,
    pub page_faults: u64,
}

CPU time, peak memory, and page faults for the current process.

All values are totals since the process started. To get the usage of one part of a program, take a sample before and after it and subtract.

Fields

user_ms: u64

CPU time in user mode, in milliseconds.

system_ms: u64

CPU time in kernel mode, in milliseconds.

peak_rss: u64

Peak resident set size, in bytes.

page_faults: u64

Minor and major page faults.

Implementations

impl ProcessStats

pub fn current() -> Self

Samples the resource usage of the current process.

Panics

Panics if getrusage fails. POSIX lets it fail only for a bad argument, so this does not occur in practice.

Trait Implementations

impl Clone for ProcessStats

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 ProcessStats

impl Debug for ProcessStats

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

Formats the value using the given formatter.

impl Default for ProcessStats

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ProcessStats

impl PartialEq for ProcessStats

fn eq(&self, other: &Self) -> bool

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
