Struct ProcList 

pub struct ProcList { /* private fields */ }

Process list. It can be viewed as a list of process or a list of process trees.

Implementations

impl ProcList

pub fn parent_of(&self, pid: Pid) -> Option<&Process>

Gets parent process’ pid of the process the pid of which is given.

pub fn procs(&self) -> impl Iterator<Item = &ProcNode>

Returns all detected running processes.

Examples

.............
.  ProcList .
.   /   \   .
.  1     4  .
. / \   / \ .
.2   3 5   6.
.............

This method will returns #1, #2, #3, #4, #5, #6.

pub fn children<'a, 's: 'a>(&'s self) -> Proc<'a>

Returns all detected running process trees.

Examples

.............
.  ProcList .
.   /   \   .
.  1     4  .
. / \   / \ .
.2   3 5   6.
.............

This method will returns #1 and #4.

Use .children() recursively to get descendant processes, e.g. #2.

pub fn bfs<'a, 's: 'a>(&'s self) -> BfsForest<Splitted<Proc<'a>>>

Returns processes in breadth first search. This method helps to convert ProcList into trees::Forest.

See trees for more.
