Struct DateTime

pub struct DateTime(/* private fields */);

Representation of a date and time in the local time zone.

Implementations

impl DateTime

pub fn new(date: (i32, u32, u32), time: (u32, u32, u32)) -> Result<Self>

Create a DateTime from two tuples, one representing the date (year, month, day) and the second representing the time (hour, minute, second).

Errors

Return an DateError::InvalidDate if the values in the tuples are not appropriate for the data types.

pub fn now() -> Self

Create a Date for right now.

impl DateTime

pub fn timestamp(&self) -> i64

Return the epoch time representing the current value of the DateTime object.

pub fn date(&self) -> Date

Return a copy of just the Date portion of the DateTime object.

pub fn hour(&self) -> u32

Return the hour of the day.

pub fn minute(&self) -> u32

Return the minute of the hour.

pub fn second_offset(&self) -> u32

Return the number of seconds after the hour.

pub fn hhmm(&self) -> String

Return the formatted time as a String

impl DateTime

pub fn seconds(seconds: u64) -> Duration

Return a Duration lasting the supplied number of minutes.

pub fn minutes(minutes: u64) -> Duration

Return a Duration lasting the supplied number of minutes.

pub fn hours(hours: u64) -> Duration

Return a Duration lasting the supplied number of hours.

pub fn days(days: u64) -> Duration

Return a Duration lasting the supplied number of days.

pub fn weeks(weeks: u64) -> Duration

Return a Duration lasting the supplied number of weeks.

Trait Implementations

impl Add<Duration> for DateTime

fn add(self, rhs: Duration) -> Result<Self>

Return a DateTime as a Result resulting from adding the rhs Duration to the object.

Errors

Return an DateError::InvalidDate if adding the duration results in a bad date.

type Output = Result<DateTime, DateError>

The resulting type after applying the + operator.

impl Clone for DateTime

fn clone(&self) -> DateTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DateTime

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

Formats the value using the given formatter.

impl Display for DateTime

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

Format a DateTime object in “YYYY-MM-DD HH:MM:DD” format.

impl From<DateTime> for String

fn from(datetime: DateTime) -> Self

Convert a Date into a String

impl Ord for DateTime

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

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

fn partial_cmp(&self, other: &DateTime) -> 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<Duration> for DateTime

fn sub(self, rhs: Duration) -> Result<Self>

Return a DateTime as a Result resulting from subtracting the rhs Duration from the object.

Errors

Return an DateError::InvalidDate if adding the duration results in a bad date.

type Output = Result<DateTime, DateError>

The resulting type after applying the - operator.

impl Sub for DateTime

fn sub(self, rhs: Self) -> Result<Duration>

Return the Duration as a Result resulting from subtracting the rhs from the object.

Errors

Return an DateError::EntryOrder if the rhs is larger than the DateTime.

type Output = Result<Duration, DateError>

The resulting type after applying the - operator.

impl TryFrom<&str> for DateTime

fn try_from(datetime: &str) -> Result<Self>

Parse the DateTime out of a string, returning a Result

Errors

If the datetime is not formatted as ‘YYYY-MM-DD HH:MM:SS’, returns an DateError::InvalidDate. Also if the datetime cannot be converted into a DateTime, returns an DateError::InvalidDate.

type Error = DateError

The type returned in the event of a conversion error.
