pub struct Procs { /* private fields */ }

Implementations

impl Procs

pub fn new() -> Self

pub fn title(&self, pid: u32) -> Option<String>

pub fn is_running(&self, pid: u32) -> bool

pub fn all_children(&self, pid: u32) -> Vec<u32>

Walk the /proc tree to find all descendant PIDs. Kept for diagnostics/status display; no longer used in the kill path.

pub fn collect_process_tree_info( &self, ) -> (HashMap<u32, Vec<u32>>, HashMap<u32, (String, Option<String>)>)

Collect minimal process tree information in a single lock.

Returns a map of parent PID → child PIDs and a map of PID → (name, exe). This avoids repeated mutex locking when traversing deep trees.

pub async fn kill_process_group_async( &self, pid: u32, stop_signal: i32, stop_timeout: Option<Duration>, ) -> Result<bool>

pub async fn kill_async( &self, pid: u32, stop_signal: i32, stop_timeout: Option<Duration>, ) -> Result<bool>

pub fn get_batch_group_stats( &self, pids: &[u32], ) -> Vec<(u32, Option<ProcessStats>)>

Get aggregated stats for multiple process trees in a single pass.

Builds the parent→children map once (O(N)) and then BFS-es from each root PID (O(D_i) per daemon). Total cost is O(N + ΣD_i) instead of O(D × N) when collecting stats for each daemon separately.

pub fn refresh_and_get_batch_stats( &self, pids: &[u32], ) -> HashMap<u32, ProcessStats>

Refresh the process tree, then call Self::get_batch_group_stats.

Convenience wrapper that guarantees get_batch_group_stats sees a fresh snapshot of /proc (or its equivalent). Returns a PID → ProcessStats map so callers do not have to repeat the same filter_map/collect boilerplate.

pub fn get_batch_tree_stats_map( &self, pids: &[u32], ) -> HashMap<u32, ProcessStats>

Get process-tree stats for multiple root PIDs, omitting roots that no longer exist.

pub fn get_stats(&self, pid: u32) -> Option<ProcessStats>

Get process-tree stats (cpu%, memory bytes, uptime secs, disk I/O) for a given root PID.

pub fn get_extended_stats(&self, pid: u32) -> Option<ExtendedProcessStats>

Get extended process information for a given PID

Trait Implementations

impl Default for Procs

fn default() -> Self

Returns the “default value” for a type.
