Enum PreciseDateTime

pub enum PreciseDateTime {
    Naive(NaiveDateTime),
    TimeZone(DateTime<FixedOffset>),
}

An encapsulated date-time value which is precise to the microsecond and can either be time-zone aware or time-zone naive.

It is usually the outcome of converting a precise DICOM date-time value to a chrono date-time value.

Variants

Naive(NaiveDateTime)

Naive date-time, with no time zone

TimeZone(DateTime<FixedOffset>)

Date-time with a time zone defined by a fixed offset

Implementations

impl PreciseDateTime

pub fn as_datetime(&self) -> Option<&DateTime<FixedOffset>>

Retrieves a reference to a chrono::DateTime<FixedOffset> if the result is time-zone aware.

pub fn as_naive_datetime(&self) -> Option<&NaiveDateTime>

Retrieves a reference to a chrono::NaiveDateTime only if the result is time-zone naive.

pub fn into_datetime(self) -> Option<DateTime<FixedOffset>>

Moves out a chrono::DateTime<FixedOffset> if the result is time-zone aware.

pub fn into_naive_datetime(self) -> Option<NaiveDateTime>

Moves out a chrono::NaiveDateTime only if the result is time-zone naive.

pub fn to_naive_date(&self) -> NaiveDate

Retrieves the time-zone naive date component of the precise date-time value.

Panics

The time-zone aware variant uses DateTime, which internally stores the date and time in UTC with a NaiveDateTime. This method will panic if the offset from UTC would push the local date outside of the representable range of a NaiveDate.

pub fn to_naive_time(&self) -> NaiveTime

Retrieves the time component of the precise date-time value.

pub fn has_time_zone(&self) -> bool

Returns true if the result is time-zone aware.

Trait Implementations

impl Clone for PreciseDateTime

fn clone(&self) -> PreciseDateTime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PreciseDateTime

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

Formats the value using the given formatter.

impl Hash for PreciseDateTime

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 PartialEq for PreciseDateTime

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

The partial ordering for PreciseDateTime is defined by the partial ordering of matching variants (Naive with Naive, TimeZone with TimeZone).

Any other comparison cannot be defined, and therefore will always return None.

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

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.
