Struct MemorySnapshot 

pub struct MemorySnapshot {
    pub rss_bytes: usize,
    pub vms_bytes: usize,
}

A snapshot of memory usage at a point in time.

Fields

rss_bytes: usize

Resident set size in bytes (physical memory used).

vms_bytes: usize

Virtual memory size in bytes.

Implementations

impl MemorySnapshot

pub fn current() -> Self

Take a snapshot of current process memory usage.

On Linux, reads /proc/self/status for VmRSS and VmSize. On other platforms, returns zero values.

pub fn rss_display(&self) -> String

Returns RSS formatted as a human-readable string.

pub fn vms_display(&self) -> String

Returns VMS formatted as a human-readable string.

Trait Implementations

impl Clone for MemorySnapshot

fn clone(&self) -> MemorySnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemorySnapshot

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

Formats the value using the given formatter.

impl Display for MemorySnapshot

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

Formats the value using the given formatter.

impl PartialEq for MemorySnapshot

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