Struct sysinfo::Pid

source · 
pub struct Pid(/* private fields */);
Expand description

Process ID.

Can be used as an integer type by simple casting. For example:

use sysinfo::Pid;

// 0's type will be different depending on the platform!
let p = Pid::from(0);

// For something more "general":
let p = Pid::from_u32(0);
let i: u32 = p.as_u32();

On glibc systems this is a glibc pid_t.

On Windows systems this is a usize and represents a windows process identifier.

On unsupported systems, this is also a usize.

Implementations§

source§

impl Pid

source

pub fn as_u32(self) -> u32

Allows to convert Pid into [u32].

use sysinfo::Pid;

let pid = Pid::from_u32(0);
let value: u32 = pid.as_u32();
source

pub fn from_u32(v: u32) -> Self

Allows to convert a [u32] into Pid.

use sysinfo::Pid;

let pid = Pid::from_u32(0);
