    type Duration;

    // Required methods
    fn to_utc(&self) -> Option<DateTime<Utc>>;

    fn sub_duration(&self, duration: Self::Duration) -> Self;
}

Trait for types that represent a point in time.

Types implementing this trait can be used as time instants in Interval<T> and provide conversions to/from UTC plus basic arithmetic operations.

Required Associated Types

type Duration

The duration type used for arithmetic operations.

Required Methods

fn to_utc(&self) -> Option<DateTime<Utc>>

Convert this time instant to UTC DateTime.

fn from_utc(datetime: DateTime<Utc>) -> Self

Create a time instant from UTC DateTime.

fn difference(&self, other: &Self) -> Self::Duration

Compute the difference between two time instants.

fn add_duration(&self, duration: Self::Duration) -> Self

Add a duration to this time instant.

fn sub_duration(&self, duration: Self::Duration) -> Self

Subtract a duration from this time instant.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
