Struct Duration

pub struct Duration { /* private fields */ }

A wrapper for a duration.

Does not count in days, but can have hours >24 (up to u32::MAX)

Precise to second-level.

Cannot be negative.

Implementations

impl Duration

pub fn new(h: u32, m: u32, s: u32) -> Duration

Produces a new Duration.

The value is calculated from total number of seconds so a duration with a minute value of 90 would add an hour to the resulting tuple and set the minutes to 30, for example.

pub fn from_seconds(total_seconds: u64) -> Duration

Same as Duration::new() but takes the total number of seconds as its argument and calculates the hours, minutes, and seconds from that.

pub fn between(dt1: DateTimeTuple, dt2: DateTimeTuple) -> Duration

Calculates the Duration between two DateTimeTuples.

pub fn get_hours(self) -> u32

pub fn get_minutes(self) -> u8

pub fn get_seconds(self) -> u8

pub fn to_hhmm_string(self) -> String

Produces a string such as 8:30 for 8 hours and 30 minutes.

Hours field will expand as necessary; 150:30 is a possible result.

Ignores seconds.

pub fn to_hours_and_minutes_string(self) -> String

👎Deprecated since 2.1.0: Replace with to_hhmm_string()

Produces a string such as 8:30 for 8 hours and 30 minutes.

Hours field will expand as necessary; 150:30 is a possible result.

Ignores seconds.

pub fn to_seconds(self) -> u64

Gets the total number of seconds in the Duration.

pub fn to_minutes(self) -> u32

Gets the total number of minutes in the Duration, ignoring seconds.

pub fn add_seconds(&mut self, seconds: u32)

Adds a number of seconds to the Duration, wrapping the same way Duration::new() does.

pub fn subtract_seconds(&mut self, seconds: u32)

Subtracts a number of seconds from the Duration, wrapping the same way Duration::new() does.

pub fn add_minutes(&mut self, minutes: u32)

Adds a number of minutes to the Duration, wrapping the same way Duration::new() does.

pub fn subtract_minutes(&mut self, minutes: u32)

Subtracts a number of minutes from the Duration, wrapping the same way Duration::new() does.

pub fn add_hours(&mut self, hours: u32)

Adds a number of hours to the Duration, wrapping the same way Duration::new() does.

pub fn subtract_hours(&mut self, hours: u32)

Subtracts a number of hours from the Duration, wrapping the same way Duration::new() does.

Trait Implementations

impl Add for Duration

type Output = Duration

The resulting type after applying the + operator.

fn add(self, other: Duration) -> Duration

Performs the + operation.

impl AddAssign for Duration

fn add_assign(&mut self, other: Duration)

Performs the += operation.

impl Clone for Duration

fn clone(&self) -> Duration

Returns a duplicate 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 Display for Duration

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

Formats the value using the given formatter.

impl From<TimeTuple> for Duration

fn from(time: TimeTuple) -> Self

Converts to this type from the input type.

impl FromStr for Duration

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Duration, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Duration

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

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

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

impl Sub for Duration

type Output = Duration

The resulting type after applying the - operator.

fn sub(self, other: Duration) -> Duration

Performs the - operation.

impl SubAssign for Duration

fn sub_assign(&mut self, other: Duration)

Performs the -= operation.

impl Copy for Duration

impl Eq for Duration
