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 -eo.

summary: ProcessSummary

Aggregated summary statistics.

Implementations

impl ProcessSnapshot

pub fn capture() -> Self

Captures a full process snapshot via ps with explicit format.

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

pub fn zombies(&self) -> Vec<&ProcessInfo>

Returns all zombie processes with their PID, command, and PPID.

Zombies are defunct child processes whose parent has not yet called waitpid(2). They consume no resources but each occupies a PID slot.

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.

Trait Implementations

impl Clone for ProcessSnapshot

fn clone(&self) -> ProcessSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcessSnapshot

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ProcessSnapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
