Struct ProcessSnapshot 

pub struct ProcessSnapshot {
    pub timestamp: u64,
    pub processes: Vec<ProcessInfo>,
    pub summary: ProcessSummary,
}

Process list snapshot at a point in time.

Contains the raw process list, a computed summary, and a timestamp.

Fields

timestamp: u64

Unix timestamp (seconds) when the snapshot was taken.

processes: Vec<ProcessInfo>

Individual process records parsed from ps aux.

summary: ProcessSummary

Aggregated summary statistics.

Implementations

impl ProcessSnapshot

pub fn capture() -> Self

Captures a full process snapshot via ps aux.

Results are cached for 30 seconds to avoid re-parsing ps aux on repeated calls within the same execution window.

pub fn clear_cache()

Clears the process snapshot cache.

Use before capturing an after-kill snapshot to ensure fresh data.

pub fn top_by_cpu(&self, n: usize) -> Vec<&ProcessInfo>

Returns the top n processes by CPU usage.

pub fn top_by_mem(&self, n: usize) -> Vec<&ProcessInfo>

Returns the top n processes by memory usage.

pub fn print_report(&self)

Prints a human-readable process report to stdout.
