Struct PackedHijriYearInfo

Source
#[repr(C, packed(1))]
pub struct PackedHijriYearInfo(pub u8, pub u8);
Expand description

The struct containing compiled Hijri YearInfo

Bit structure (little endian: note that shifts go in the opposite direction!)

Bit:             0   1   2   3   4   5   6   7
Byte 0:          [  month lengths .............
Byte 1:         .. months    ] | [ ny offset    ]

Where the New Year Offset is a signed offset from epoch + MEAN_SYNODIC_MONTH * year * 12 for the given calendar. 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.
