Struct Whod 

#[repr(C)]
pub struct Whod {
    pub wd_vers: u8,
    pub wd_type: u8,
    pub wd_pad: [u8; 2],
    pub wd_sendtime: i32,
    pub wd_recvtime: i32,
    pub wd_hostname: [u8; 32],
    pub wd_loadav: [i32; 3],
    pub wd_boottime: i32,
    pub wd_we: [Whoent; 42],
}

Classic C struct for a rwhod status update.

This struct is used in the rwhod protocol by being interpreted as raw bytes to be sent over UDP.

Fields

wd_vers: u8

protocol version

wd_type: u8

packet type, see below

wd_pad: [u8; 2]

wd_sendtime: i32

time stamp by sender

wd_recvtime: i32

time stamp applied by receiver

wd_hostname: [u8; 32]

host’s name

wd_loadav: [i32; 3]

load average as in uptime

wd_boottime: i32

time system booted

wd_we: [Whoent; 42]

Trait Implementations

impl Clone for Whod

fn clone(&self) -> Whod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Whod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Whod

fn eq(&self, other: &Whod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Whod> for WhodStatusUpdate

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: Whod) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WhodStatusUpdate> for Whod

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: WhodStatusUpdate) -> Result<Self, Self::Error>

Performs the conversion.
