Struct NtpTimestamp 

pub struct NtpTimestamp(pub u64);

NTP uses a 64-bit timestamp: 32-bit seconds since 1900-01-01 + 32-bit fraction. Stored as a single u64 for arithmetic efficiency. Upper 32 bits = seconds, lower 32 bits = fractional seconds.

Tuple Fields

0: u64

Implementations

impl NtpTimestamp

pub const ZERO: Self

pub fn new(seconds: u32, fraction: u32) -> Self

Create from separate seconds (since NTP epoch) and fraction parts.

pub fn now() -> Self

Create from the current system time.

pub fn from_system_time(time: SystemTime) -> Self

Convert from a SystemTime.

pub fn to_system_time(self) -> SystemTime

Convert to a SystemTime.

pub fn seconds(self) -> u32

Seconds since NTP epoch (upper 32 bits).

pub fn fraction(self) -> u32

Fractional seconds (lower 32 bits).

pub fn raw(self) -> u64

Raw 64-bit value.

pub fn from_raw(raw: u64) -> Self

Create from raw 64-bit value.

pub fn to_bytes(self) -> [u8; 8]

Serialize to 8-byte big-endian wire format.

pub fn from_bytes(bytes: [u8; 8]) -> Self

Deserialize from 8-byte big-endian wire format.

Trait Implementations

impl Clone for NtpTimestamp

fn clone(&self) -> NtpTimestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NtpTimestamp

impl Debug for NtpTimestamp

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

Formats the value using the given formatter.

impl Default for NtpTimestamp

fn default() -> NtpTimestamp

Returns the “default value” for a type.

impl Display for NtpTimestamp

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

Formats the value using the given formatter.

impl Eq for NtpTimestamp

impl Hash for NtpTimestamp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NtpTimestamp

fn cmp(&self, other: &NtpTimestamp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NtpTimestamp

fn eq(&self, other: &NtpTimestamp) -> 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 PartialOrd for NtpTimestamp

fn partial_cmp(&self, other: &NtpTimestamp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
