Resident set size, in KiB.

peak_rss_kb: Option<u64>

Peak resident set size, in KiB.

vsize_kb: Option<u64>

Virtual memory size, in KiB.

peak_vsize_kb: Option<u64>

Peak virtual memory size, in KiB.

threads: Option<u64>

Current thread count for the process.

Implementations

impl MemorySnapshot

pub fn capture() -> Self

Capture a snapshot of the current process’s memory usage.

Returns a default-filled snapshot (all None) on non-Linux targets or when /proc/self/status is unreadable.

pub fn parse(text: &str) -> Self

Parse /proc/self/status-style content.

Only VmRSS, VmHWM, VmSize, VmPeak, and Threads are extracted.

Examples

use codetether_agent::telemetry::memory::MemorySnapshot;

let text = "VmRSS:\t 1234 kB\nVmHWM:\t 2345 kB\nThreads:\t   7\n";
let snap = MemorySnapshot::parse(text);
assert_eq!(snap.rss_kb, Some(1234));
assert_eq!(snap.peak_rss_kb, Some(2345));
assert_eq!(snap.threads, Some(7));

pub fn rss_mib(&self) -> Option<u64>

RSS in MiB, rounded down. Returns None if RSS is unavailable.
