Struct PackedHijriYearData 

struct PackedHijriYearData(u16);

The struct containing compiled Hijri YearInfo

• start_day has to be within 5 days of the start of the year of the TabularAlgorithm.
• month_lengths[n - 1] has either 6 or 7 long months.

Bit structure

Bit:              F.........C  B.............0
Value:           [ start day ][ month lengths ]

The start day is encoded as a signed offset from Self::mean_tabular_start_day. This number does not appear to be less than 2, however we use all remaining bits for it in case of drift in the math. The month lengths are stored as 1 = 30, 0 = 29 for each month including the leap month.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Trait Implementations

impl Clone for PackedHijriYearData

fn clone(&self) -> PackedHijriYearData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PackedHijriYearData

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

Formats the value using the given formatter.

impl Hash for PackedHijriYearData

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 Ord for PackedHijriYearData

fn cmp(&self, other: &PackedHijriYearData) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PackedHijriYearData

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

impl PartialOrd for PackedHijriYearData

fn partial_cmp(&self, other: &PackedHijriYearData) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
