Struct DateRange

pub struct DateRange { /* private fields */ }

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

Example

use chrono::NaiveDate;
use dicom_core::value::DateRange;

let dr = DateRange::from_start(NaiveDate::from_ymd_opt(2000, 5, 3).unwrap());

assert!(dr.start().is_some());
assert!(dr.end().is_none());

Implementations

impl DateRange

pub fn from_start_to_end( start: NaiveDate, end: NaiveDate, ) -> Result<DateRange, Error>

Constructs a new DateRange from two chrono::NaiveDate values monotonically ordered in time.

pub fn from_start(start: NaiveDate) -> DateRange

Constructs a new DateRange beginning with a chrono::NaiveDate value and no upper limit.

pub fn from_end(end: NaiveDate) -> DateRange

Constructs a new DateRange with no lower limit, ending with a chrono::NaiveDate value.

pub fn start(&self) -> Option<&NaiveDate>

Returns a reference to lower bound of range.

pub fn end(&self) -> Option<&NaiveDate>

Returns a reference to upper bound of range.

Trait Implementations

impl Clone for DateRange

fn clone(&self) -> DateRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DateRange

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

Formats the value using the given formatter.

impl Hash for DateRange

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 DateRange

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