Struct icu::calendar::provider::islamic::PackedIslamicYearInfo

#[repr(C, packed(1))]
pub struct PackedIslamicYearInfo(pub u8, pub u8);

The struct containing compiled Islamic 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.

impl Ord for PackedIslamicYearInfo

fn cmp(&self, other: &PackedIslamicYearInfo) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PackedIslamicYearInfo

fn eq(&self, other: &PackedIslamicYearInfo) -> 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 PackedIslamicYearInfo

fn partial_cmp(&self, other: &PackedIslamicYearInfo) -> 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.

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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ULE for PackedIslamicYearInfo

fn validate_bytes(bytes: &[u8]) -> Result<(), UleError>

Validates a byte slice, &[u8].

fn parse_bytes_to_slice(bytes: &[u8]) -> Result<&[Self], UleError>

unsafe fn slice_from_bytes_unchecked(bytes: &[u8]) -> &[Self]

Takes a byte slice, &[u8], and return it as &[Self] with the same lifetime, assuming that this byte slice has previously been run through Self::parse_bytes_to_slice() with success.

fn slice_as_bytes(slice: &[Self]) -> &[u8]

Given &[Self], returns a &[u8] with the same lifetime.
