Struct Pid 

pub struct Pid(/* private fields */);

A process ID (PID).

Implementations

impl Pid

pub fn from_raw(pid: pid_t) -> Self

Creates Pid from a raw pid_t.

pub fn this() -> Self

Returns the PID of the calling process.

pub fn parent() -> Self

Returns the PID of the calling process.

pub fn as_raw(self) -> pid_t

Gets the raw pid_t from this Pid.

pub fn colored(self) -> ColoredPid

Returns a Displayable that is color-coded. That is, the same PID will get the same color. This makes it easy to visually recognize PIDs when looking through logs.

Note that while the same PIDs always have the same color, different PIDs may also have the same color if they fall into the same color bucket.
