Struct WallMicros 

pub struct WallMicros(pub i64);

A wall-clock instant, in microseconds since the Unix epoch.

This is a coordinate on the time line and not an extent of time, so it is a newtype here and not a [krabka_units::Time]. See the code style guide’s “Dimensioned Values” section for the rule.

The unit is the microsecond. A Kafka record timestamp counts milliseconds, and one millisecond is too coarse to order the records inside one batch. A microsecond gives the logical counter far fewer events to separate.

The value is signed, and a value below zero names an instant before the Unix epoch. The clock accepts such a value and does not treat it as an error, because a host whose clock is unset reports one.

Implementations

impl WallMicros

pub const EPOCH: Self

The Unix epoch, 1970-01-01T00:00:00Z.

pub const fn get(self) -> i64

The inner i64. Use it for arithmetic against other time counts.

Performs copy-assignment from source.

impl Copy for WallMicros

impl Debug for WallMicros

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

Formats the value using the given formatter.

impl Default for WallMicros

fn default() -> WallMicros

Returns the “default value” for a type.

impl Display for WallMicros

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

impl Eq for WallMicros

impl From<WallMicros> for i64

fn from(value: WallMicros) -> Self

Converts to this type from the input type.

impl From<i64> for WallMicros

fn from(value: i64) -> Self

Converts to this type from the input type.

impl Hash for WallMicros

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 WallMicros

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

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

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