Implementations

impl OpeningHoursExpression

pub fn is_constant(&self) -> bool

Check if this expression is trivially constant (ie. always evaluated at the exact same status). Note that this may return false for an expression that is constant but should cover most common cases.

use opening_hours_syntax::parse;

assert!(parse("24/7").unwrap().is_constant());
assert!(parse("24/7 closed").unwrap().is_constant());
assert!(parse("00:00-24:00 open").unwrap().is_constant());
assert!(!parse("00:00-18:00 open").unwrap().is_constant());
assert!(!parse("24/7 ; PH off").unwrap().is_constant());

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.

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

Trait Implementations

impl Clone for OpeningHoursExpression

fn clone(&self) -> OpeningHoursExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpeningHoursExpression

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

Formats the value using the given formatter.

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

Formats the value using the given formatter.

impl Hash for OpeningHoursExpression

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,

impl PartialEq for OpeningHoursExpression

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