An Arrow TimeZone

Trait Implementations

impl Clone for Tz

fn clone(&self) -> Tz

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tz

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

Formats the value using the given formatter.

impl FromStr for Tz

type Err = ArrowError

The associated error which can be returned from parsing.

fn from_str(tz: &str) -> Result<Tz, <Tz as FromStr>::Err>

Parses a string s to return a value of this type.

impl TimeZone for Tz

type Offset = TzOffset

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: &<Tz as TimeZone>::Offset) -> Tz

Reconstructs the time zone from the offset.

fn offset_from_local_date( &self, local: &NaiveDate ) -> LocalResult<<Tz as TimeZone>::Offset>

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

fn offset_from_local_datetime( &self, local: &NaiveDateTime ) -> LocalResult<<Tz as TimeZone>::Offset>

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

fn offset_from_utc_date(&self, utc: &NaiveDate) -> <Tz as TimeZone>::Offset

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

fn offset_from_utc_datetime( &self, utc: &NaiveDateTime ) -> <Tz as TimeZone>::Offset

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

fn with_ymd_and_hms( &self, year: i32, month: u32, day: u32, hour: u32, min: u32, sec: u32 ) -> LocalResult<DateTime<Self>>

Make a new DateTime from year, month, day, time components and current time zone.

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

👎Deprecated since 0.4.23: use with_ymd_and_hms() instead

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>>

👎Deprecated since 0.4.23: use with_ymd_and_hms() instead

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>

👎Deprecated since 0.4.23: use from_local_datetime() with a NaiveDateTime instead

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>>

👎Deprecated since 0.4.23: use from_local_datetime() with a NaiveDateTime instead

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>

👎Deprecated since 0.4.23: use from_local_datetime() with a NaiveDateTime instead

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>>

👎Deprecated since 0.4.23: use from_local_datetime() with a NaiveDateTime instead

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>

👎Deprecated since 0.4.23: use timestamp_opt() instead

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>

👎Deprecated since 0.4.23: use timestamp_millis_opt() instead

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 timestamp_micros(&self, micros: i64) -> LocalResult<DateTime<Self>>

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

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

👎Deprecated since 0.4.29: use DateTime::parse_from_str or NaiveDateTime::parse_from_str with and_utc() or and_local_timezone() instead

Parses a string with the specified format string and returns a DateTime with the current offset.

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

👎Deprecated since 0.4.23: use from_local_datetime() instead

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>

👎Deprecated since 0.4.23: use from_utc_datetime() instead

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).
