Struct Offset 

pub struct Offset { /* private fields */ }

Type-safe alias for time value representing an offset.

Implementations

impl Offset

pub const fn from_time_zero(delta: Duration) -> Offset

Given a duration delta, returns an offset X such that the half-open interval [0, X) has length delta.

pub const fn closed_from_time_zero(delta: Duration) -> Offset

Given a duration delta, returns an offset X such that the closed interval [0, X] has length delta.

pub const fn since_time_zero(self) -> Duration

Given an offset X, returns the length of the half-open interval [0, X).

Example

let t = Offset::from(10);
assert_eq!(Offset::from_time_zero(t.since_time_zero()), t);

pub const fn closed_since_time_zero(self) -> Duration

Given an offset X, returns the length of the closed interval [0, X].

Example

let t = Offset::from(10);
assert_eq!(Offset::closed_from_time_zero(t.closed_since_time_zero()), t);

pub fn distance_to(self, t: Offset) -> Duration

Compute the distance to a later point in time.

Example:

let a = Offset::from(10);
let b = Offset::from(25);
assert_eq!(a + a.distance_to(b), b);

Trait Implementations

impl Add<Duration> for Offset

type Output = Offset

The resulting type after applying the + operator.

fn add(self, delta: Duration) -> Offset

Performs the + operation.

impl Clone for Offset

fn clone(&self) -> Offset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Offset

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

Formats the value using the given formatter.

impl Display for Offset

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

Formats the value using the given formatter.

impl From<Offset> for Time

fn from(original: Offset) -> Self

Converts to this type from the input type.

impl From<u64> for Offset

fn from(original: Time) -> Offset

Converts to this type from the input type.

impl Ord for Offset

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

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

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