Struct icu_calendar::provider::chinese_based::PackedChineseBasedYearInfo

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

The struct containing compiled ChineseData

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:         .. month lengths ] | [ leap month index ..
Byte 2:          ] | [   NY offset       ] | unused

Where the New Year Offset is the offset from ISO Jan 21 of that year for Chinese New Year, the month lengths are stored as 1 = 30, 0 = 29 for each month including the leap month. The largest possible offset is 33, which requires 6 bits of storage.

🚧 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.

type ULE = PackedChineseBasedYearInfo

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self

Converts from Self to Self::ULE.

fn from_unaligned(other: Self) -> Self

Converts from Self::ULE to Self.

impl Bake for PackedChineseBasedYearInfo

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl BakeSize for PackedChineseBasedYearInfo

fn borrows_size(&self) -> usize

Returns the size

impl Clone for PackedChineseBasedYearInfo

fn clone(&self) -> PackedChineseBasedYearInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackedChineseBasedYearInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PackedChineseBasedYearInfo

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for PackedChineseBasedYearInfo

fn cmp(&self, other: &PackedChineseBasedYearInfo) -> 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 PackedChineseBasedYearInfo

fn eq(&self, other: &PackedChineseBasedYearInfo) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PackedChineseBasedYearInfo

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for PackedChineseBasedYearInfo

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl ULE for PackedChineseBasedYearInfo

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

Validates a byte slice, &[u8].

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

Parses a byte slice, &[u8], and return it as &[Self] with the same lifetime.

unsafe fn from_byte_slice_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_byte_slice()] with success.

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

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