Struct Wall 

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

Available on crate feature std only.

A captured wall-clock instant.

Wall wraps a single sample of the operating system’s real-time clock. Convert it to Unix time with unix_seconds, unix_millis, or unix_nanos.

Wall and Monotonic are deliberately distinct types and cannot be mixed. If your system clock predates the Unix epoch (1970-01-01 UTC), the unix_* accessors saturate at zero — they never panic and never silently wrap.

Construct one with Wall::now or the crate-level wall shortcut.

Examples

use clock_lib::Wall;

let stamp = Wall::now();
let seconds = stamp.unix_seconds();
assert!(seconds > 0);

Implementations

impl Wall

pub fn now() -> Self

Captures the current wall-clock time from the operating system.

This is the constructor for Wall. The crate-level wall function is a one-line shortcut for the same thing.

Examples

use clock_lib::Wall;

let stamp = Wall::now();

pub fn unix_seconds(self) -> u64

Returns Unix time in whole seconds.

Returns zero if the system clock is set to a moment before the Unix epoch. The return type is u64, which is sufficient to represent any plausible wall-clock value through year 584,942,417,355 — Unix time will not overflow this accessor.

Examples

use clock_lib::Wall;

let seconds = Wall::now().unix_seconds();
assert!(seconds > 0);

pub fn unix_millis(self) -> u128

Returns Unix time in whole milliseconds.

Returns zero if the system clock is set to a moment before the Unix epoch. The return type is u128, which cannot overflow for any representable SystemTime.

Examples

use clock_lib::Wall;

let millis = Wall::now().unix_millis();
assert!(millis > 0);

pub fn unix_nanos(self) -> u128

Returns Unix time in whole nanoseconds.

Returns zero if the system clock is set to a moment before the Unix epoch. The return type is u128, which cannot overflow for any representable SystemTime.

Examples

use clock_lib::Wall;

let nanos = Wall::now().unix_nanos();
assert!(nanos > 0);

Trait Implementations

impl Clone for Wall

fn clone(&self) -> Wall

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Wall

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

Formats the value using the given formatter.

impl Hash for Wall

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 Wall

fn cmp(&self, other: &Wall) -> 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 Wall

fn eq(&self, other: &Wall) -> 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 Wall

fn partial_cmp(&self, other: &Wall) -> 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.
