This trait defines the operations that can be performed on a TimeExtent.

Required Associated Types

type Base

type Multiplier

type Product

Required Methods

fn new(unit: &Self::Base, count: &Self::Multiplier) -> Self

It creates a new TimeExtent.

fn increase(&self, add: Self::Multiplier) -> Result<Self, IntErrorKind>

It increases the TimeExtent by a multiplier.

Errors

Will return IntErrorKind if add would overflow the internal Duration.

fn decrease(&self, sub: Self::Multiplier) -> Result<Self, IntErrorKind>

It decreases the TimeExtent by a multiplier.

Errors

Will return IntErrorKind if sub would underflow the internal Duration.

fn total(&self) -> Option<Result<Self::Product, TryFromIntError>>

It returns the total Duration of the TimeExtent.

fn total_next(&self) -> Option<Result<Self::Product, TryFromIntError>>

It returns the total Duration of the TimeExtent plus one increment.

Object Safety

This trait is not object safe.

Implementors
