Struct dicom_core::value::range::DateTimeRange

pub struct DateTimeRange { /* private fields */ }

Represents a date-time range as two Option<chrono::DateTime<FixedOffset>> values. None means no upper or no lower bound for range is present.

Example

use chrono::{NaiveDate, NaiveTime, NaiveDateTime, DateTime, FixedOffset, TimeZone};
use dicom_core::value::DateTimeRange;

let offset = FixedOffset::west_opt(3600).unwrap();

let dtr = DateTimeRange::from_start_to_end(
    offset.from_local_datetime(&NaiveDateTime::new(
        NaiveDate::from_ymd_opt(2000, 5, 6).unwrap(),
        NaiveTime::from_hms_opt(15, 0, 0).unwrap()
    )).unwrap(),
    offset.from_local_datetime(&NaiveDateTime::new(
        NaiveDate::from_ymd_opt(2000, 5, 6).unwrap(),
        NaiveTime::from_hms_opt(16, 30, 0).unwrap()
    )).unwrap()
)?;

assert!(dtr.start().is_some());
assert!(dtr.end().is_some());

Implementations

impl DateTimeRange

pub fn from_start_to_end(
    start: DateTime<FixedOffset>,
    end: DateTime<FixedOffset>
) -> Result<DateTimeRange, Error>

Constructs a new DateTimeRange from two chrono::DateTime values monotonically ordered in time.

pub fn from_start(start: DateTime<FixedOffset>) -> DateTimeRange

Constructs a new DateTimeRange beginning with a chrono::DateTime value and no upper limit.

pub fn from_end(end: DateTime<FixedOffset>) -> DateTimeRange

Constructs a new DateTimeRange with no lower limit, ending with a chrono::DateTime value.

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

Returns a reference to the lower bound of the range.

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

Returns a reference to the upper bound of the range.

pub fn from_date_and_time_range(
    dr: DateRange,
    tr: TimeRange,
    offset: FixedOffset
) -> Result<DateTimeRange, Error>

For combined datetime range matching, this method constructs a DateTimeRange from a DateRange and a TimeRange.

Trait Implementations

impl Clone for DateTimeRange

fn clone(&self) -> DateTimeRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateTimeRange

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

Formats the value using the given formatter.

impl Hash for DateTimeRange

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<DateTimeRange> for DateTimeRange

fn eq(&self, other: &DateTimeRange) -> 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.
