Struct `Pid`

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

Process identifier

Newtype pattern around pid_t (which is just alias). It prevents bugs caused by accidentally passing wrong value.

Implementations

`impl Pid`

const fn from_raw(pid: pid_t) -> Self: Creates Pid from raw pid_t.
fn this() -> Self: Returns PID of calling process
fn parent() -> Self: Returns PID of parent of calling process
const fn as_raw(self) -> pid_t: Get the raw pid_t wrapped by self.
