Struct circadian_time::Circadian

pub struct Circadian<P: Positioned> { /* fields omitted */ }

The Circadian timezone. This timezone aligns to dawn instead of noon. At dawn the circadian time will be 00:00.

Methods

impl<P: Positioned> Circadian<P>

pub fn now() -> DateTime<Self>

Get the current circadian time.

Trait Implementations

impl<P: Clone + Positioned> Clone for Circadian<P>

fn clone(&self) -> Circadian<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Debug + Positioned> Debug for Circadian<P>

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

Formats the value using the given formatter.

impl<P: Positioned> Display for Circadian<P>

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

Formats the value using the given formatter.

impl<P: Positioned> TimeZone for Circadian<P>

type Offset = Circadian<P>

An associated offset type. This type is used to store the actual offset in date and time types. The original TimeZone value can be recovered via TimeZone::from_offset.

fn from_offset(offset: &Circadian<P>) -> Self

Reconstructs the time zone from the offset.

fn offset_from_local_date(&self, local: &NaiveDate) -> LocalResult<Circadian<P>>

Creates the offset(s) for given local NaiveDate if possible.

fn offset_from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<Circadian<P>>

Creates the offset(s) for given local NaiveDateTime if possible.

fn offset_from_utc_date(&self, utc: &NaiveDate) -> Circadian<P>

Creates the offset for given UTC NaiveDate. This cannot fail.

fn offset_from_utc_datetime(&self, utc: &NaiveDateTime) -> Circadian<P>

Creates the offset for given UTC NaiveDateTime. This cannot fail.

fn ymd(&self, year: i32, month: u32, day: u32) -> Date<Self>

Makes a new Date from year, month, day and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn ymd_opt(&self, year: i32, month: u32, day: u32) -> LocalResult<Date<Self>>

Makes a new Date from year, month, day and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn yo(&self, year: i32, ordinal: u32) -> Date<Self>

Makes a new Date from year, day of year (DOY or "ordinal") and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn yo_opt(&self, year: i32, ordinal: u32) -> LocalResult<Date<Self>>

Makes a new Date from year, day of year (DOY or "ordinal") and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn isoywd(&self, year: i32, week: u32, weekday: Weekday) -> Date<Self>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

fn isoywd_opt(
    &self,
    year: i32,
    week: u32,
    weekday: Weekday
) -> LocalResult<Date<Self>>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

fn timestamp(&self, secs: i64, nsecs: u32) -> DateTime<Self>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

fn timestamp_opt(&self, secs: i64, nsecs: u32) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

fn timestamp_millis(&self, millis: i64) -> DateTime<Self>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

fn timestamp_millis_opt(&self, millis: i64) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

fn timestamp_nanos(&self, nanos: i64) -> DateTime<Self>

Makes a new DateTime from the number of non-leap nanoseconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

fn datetime_from_str(
    &self,
    s: &str,
    fmt: &str
) -> Result<DateTime<Self>, ParseError>

Parses a string with the specified format string and returns a DateTime with the current offset. See the format::strftime module on the supported escape sequences.

fn from_local_date(&self, local: &NaiveDate) -> LocalResult<Date<Self>>

Converts the local NaiveDate to the timezone-aware Date if possible.

fn from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<DateTime<Self>>

Converts the local NaiveDateTime to the timezone-aware DateTime if possible.

fn from_utc_date(&self, utc: &NaiveDate) -> Date<Self>

Converts the UTC NaiveDate to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

fn from_utc_datetime(&self, utc: &NaiveDateTime) -> DateTime<Self>

Converts the UTC NaiveDateTime to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

impl<P: Positioned> Offset for Circadian<P>

fn fix(&self) -> FixedOffset

Returns the fixed offset from UTC to the local time stored.
