Struct dicom_core::value::range::DateTimeRange

pub struct DateTimeRange { /* fields omitted */ }

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::{DateTime, FixedOffset, TimeZone};
use dicom_core::value::DateTimeRange;

let offset = FixedOffset::west(3600);

let dtr = DateTimeRange::from_start_to_end(
    offset.ymd(2000, 5, 6).and_hms(15, 0, 0),
    offset.ymd(2000, 5, 6).and_hms(16, 30, 0)
)?;

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 lower bound of range.

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

Returns a reference to upper bound of 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.
