Struct OpeningHours

Source

pub struct OpeningHours<L: Localize = NoLocation> { /* private fields */ }

Expand description

A parsed opening hours expression and its evaluation context.

Note that all big inner structures are immutable and wrapped by an Arc so this is safe and fast to clone.

Implementations§

Source §

impl OpeningHours<NoLocation>

Source

pub fn parse(raw_oh: &str) -> Result<Self, ParserError>

Parse a raw opening hours expression.

use opening_hours::{Context, OpeningHours};

assert!(OpeningHours::parse("24/7 open").is_ok());
assert!(OpeningHours::parse("not a valid expression").is_err());

Source §

impl<L: Localize> OpeningHours<L>

Source

pub fn with_context<L2: Localize>(self, ctx: Context<L2>) -> OpeningHours<L2>

Set a new evaluation context for this expression.

use opening_hours::{Context, OpeningHours};

let oh = OpeningHours::parse("Mo-Fr open")
    .unwrap()
    .with_context(Context::default());

Source

pub fn normalize(&self) -> Self

Convert the expression into a normalized form. It will not affect the meaning of the expression and might impact the performance of evaluations.

use opening_hours::OpeningHours;

let oh = OpeningHours::parse("24/7 ; Su closed").unwrap();
assert_eq!(oh.normalize().to_string(), "Mo-Sa");

Source

pub fn schedule_at(&self, date: NaiveDate) -> Schedule

Get the schedule at a given day.

Source

pub fn iter_range( &self, from: L::DateTime, to: L::DateTime, ) -> impl Iterator<Item = DateTimeRange<L::DateTime>> + Send + Sync + use<L>

Iterate over disjoint intervals of different state restricted to the time interval from..to.

Source

pub fn iter_from( &self, from: L::DateTime, ) -> impl Iterator<Item = DateTimeRange<L::DateTime>> + Send + Sync + use<L>

Source

pub fn next_change(&self, current_time: L::DateTime) -> Option<L::DateTime>

Get the next time where the state will change.

use chrono::NaiveDateTime;

use opening_hours_syntax::RuleKind;

let oh = OpeningHours::parse("12:00-18:00 open, 18:00-20:00 unknown").unwrap();
let date_1 = NaiveDateTime::parse_from_str("2024-11-18 15:00", "%Y-%m-%d %H:%M").unwrap();
let date_2 = NaiveDateTime::parse_from_str("2024-11-18 18:00", "%Y-%m-%d %H:%M").unwrap();
assert_eq!(oh.next_change(date_1), Some(date_2));

Source

pub fn state(&self, current_time: L::DateTime) -> RuleKind

Get the state at given time.

use chrono::NaiveDateTime;

let date_2 = NaiveDateTime::parse_from_str("2024-11-18 19:00", "%Y-%m-%d %H:%M").unwrap();
assert_eq!(oh.state(date_1), RuleKind::Open);
assert_eq!(oh.state(date_2), RuleKind::Unknown);

Source

pub fn is_open(&self, current_time: L::DateTime) -> bool

Check if this is open at a given time.

use chrono::NaiveDateTime;

assert!(oh.is_open(date_1));
assert!(!oh.is_open(date_2));

Source

pub fn is_closed(&self, current_time: L::DateTime) -> bool

Check if this is closed at a given time.

use chrono::NaiveDateTime;
use opening_hours::OpeningHours;

let oh = OpeningHours::parse("12:00-18:00 open, 18:00-20:00 unknown").unwrap();
let date_1 = NaiveDateTime::parse_from_str("2024-11-18 10:00", "%Y-%m-%d %H:%M").unwrap();

let oh = OpeningHours::parse("12:00-18:00 open, 18:00-20:00 unknown").unwrap();
let date_1 = NaiveDateTime::parse_from_str("2024-11-18 19:00", "%Y-%m-%d %H:%M").unwrap();
