Enum bonsaidb::core::key::time::limited::SignedDuration

pub enum SignedDuration {
    Positive(Duration),
    Negative(Duration),
}

A Duration that can be either negative or positive.

Variants

Positive(Duration)

A duration representing a positive measurement of time.

Negative(Duration)

A duration representing a negative measurement of time.

Implementations

impl SignedDuration

pub fn checked_add(self, other: SignedDuration) -> Option<SignedDuration>

Adds the two durations, honoring the signs, and returns the result if the duration is representable.

Trait Implementations

impl Clone for SignedDuration

fn clone(&self) -> SignedDuration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignedDuration

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

Formats the value using the given formatter.

impl PartialEq for SignedDuration

fn eq(&self, other: &SignedDuration) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sum<SignedDuration> for Option<SignedDuration>

fn sum<I>(iter: I) -> Option<SignedDuration>

where I: Iterator<Item = SignedDuration>,

Method which takes an iterator and generates Self from the elements by “summing up” the items.

impl Sum for SignedDuration

fn sum<I>(iter: I) -> SignedDuration

where I: Iterator<Item = SignedDuration>,

Method which takes an iterator and generates Self from the elements by “summing up” the items.

impl<Resolution> TryFrom<LimitedResolutionDuration<Resolution>> for SignedDuration

where Resolution: TimeResolution,

type Error = TimeError

The type returned in the event of a conversion error.

fn try_from( value: LimitedResolutionDuration<Resolution> ) -> Result<SignedDuration, <SignedDuration as TryFrom<LimitedResolutionDuration<Resolution>>>::Error>

Performs the conversion.

impl<Resolution> TryFrom<SignedDuration> for LimitedResolutionDuration<Resolution>

where Resolution: TimeResolution,

type Error = TimeError

The type returned in the event of a conversion error.

fn try_from( duration: SignedDuration ) -> Result<LimitedResolutionDuration<Resolution>, <LimitedResolutionDuration<Resolution> as TryFrom<SignedDuration>>::Error>

Performs the conversion.
