Implementations

impl LogosDate

pub fn new(days: i32) -> LogosDate

Create a new date from days since Unix epoch.

pub fn from_ymd(year: i64, month: i64, day: i64) -> LogosDate

Construct a date from civil (year, month, day) via base days_from_civil — the AOT mirror of the makeDate builtin.

pub fn days(&self) -> i32

Get the raw days value.

pub fn year(&self) -> i64

UTC calendar components — AOT mirrors of year_of/month_of/day_of/weekday_of on a Date.

pub fn month(&self) -> i64

pub fn day(&self) -> i64

pub fn weekday(&self) -> i64

pub fn iso_week(&self) -> i64

The ISO-8601 week number (1..=53) — the AOT mirror of week_of on a Date.

pub fn quarter(&self) -> i64

The calendar quarter (1..=4) — the AOT mirror of quarter_of on a Date.

pub fn to_ymd(&self) -> (i64, i64, i64)

Convert to year, month, day using Howard Hinnant’s algorithm.

impl LogosDate

pub fn add_span(self, months: i32, days: i32) -> LogosDate

This date moved by a calendar span: months first (clamped to the end of the month), then days — base date_add_span, the arithmetic every tier’s Date + Span shares.

Trait Implementations

impl Add<LogosSpan> for LogosDate

type Output = LogosDate

The resulting type after applying the + operator.

fn add(self, rhs: LogosSpan) -> LogosDate

Performs the + operation.

impl Clone for LogosDate

fn clone(&self) -> LogosDate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogosDate

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

Formats the value using the given formatter.

impl Display for LogosDate

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

Formats the value using the given formatter.

impl Hash for LogosDate

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 LogosDate

fn cmp(&self, other: &LogosDate) -> 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 OtherValue for LogosDate

fn type_name(&self) -> &str

The kind’s name as the language writes it.

fn display_string(&self) -> String

How the value prints.

fn as_any(&self) -> &(dyn Any + 'static)

The value, for a kind to recognise one of its own.

fn equals(&self, o: &(dyn OtherValue + 'static)) -> bool

The language’s equality with another value of a kind outside the tower.

fn order(&self, o: &LogosValue) -> Option<Option<Ordering>>

The order of self against o, None when the language orders no such pair.

fn combine( &self, op: Op, o: &LogosValue, reversed: bool, ) -> Option<Result<LogosValue, String>>

self op o, or o op self when reversed; None when the language has no arm for the pair.

impl PartialEq for LogosDate

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

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

impl Showable for LogosDate

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

impl Sub<LogosSpan> for LogosDate

type Output = LogosDate

The resulting type after applying the - operator.

fn sub(self, rhs: LogosSpan) -> LogosDate

Performs the - operation.
