Implementations

impl Duration

pub fn new(fixed_slots: i64) -> Self

Create a new integer size Duration

pub fn parse(duration: &str) -> Self

1ns // 1 nanosecond 1us // 1 microsecond 1ms // 1 millisecond 1s // 1 second 1m // 1 minute 1h // 1 hour 1d // 1 day 1w // 1 week 1mo // 1 calendar month 1y // 1 calendar year 1i // 1 index value (only for {Int32, Int64} dtypes

3d12h4m25s // 3 days, 12 hours, 4 minutes, and 25 seconds

Panics if given str is incorrect

pub fn is_zero(&self) -> bool

true if zero duration.

pub fn months_only(&self) -> bool

pub fn months(&self) -> i64

pub fn weeks_only(&self) -> bool

pub fn weeks(&self) -> i64

pub fn days_only(&self) -> bool

pub fn days(&self) -> i64

pub fn nanoseconds(&self) -> i64

Returns the nanoseconds from the Duration without the weeks or months part.

Trait Implementations

impl Clone for Duration

fn clone(&self) -> Duration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Duration

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

Formats the value using the given formatter.

impl Hash for Duration

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 Mul<i64> for Duration

type Output = Duration

The resulting type after applying the * operator.

fn mul(self, rhs: i64) -> Self

Performs the * operation.

impl Ord for Duration

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Duration> for Duration

fn eq(&self, other: &Duration) -> 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 PartialOrd<Duration> for Duration

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
