Struct ArcTz 

pub struct ArcTz(pub Arc<Tz>);

Atomic reference-counted time zone.

This type is equivalent to Arc<Tz>, but needed to workaround Rust’s coherence rule to implement TimeZone.

Tuple Fields

0: Arc<Tz>

Implementations

impl ArcTz

pub fn new(tz: Tz) -> Self

Wraps an existing Tz object in this atomic reference-counted container.

pub fn named(name: &str) -> Result<Self>

Reads and parses a system time zone.

Equivalent to calling Tz::named() and wraps the result in this atomic reference-counted container.

This function is currently only supported on Unix.

Trait Implementations

impl Clone for ArcTz

fn clone(&self) -> ArcTz

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArcTz

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

Formats the value using the given formatter.

impl Deref for ArcTz

type Target = Tz

The resulting type after dereferencing.

fn deref(&self) -> &Tz

Dereferences the value.

impl From<Tz> for ArcTz

fn from(tz: Tz) -> Self

Converts to this type from the input type.

impl Hash for ArcTz

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

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 PartialEq for ArcTz

fn eq(&self, other: &ArcTz) -> 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 TimeZone for ArcTz

type Offset = Offset<ArcTz>

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: &Self::Offset) -> Self

Reconstructs the time zone from the offset.

fn offset_from_utc_datetime(&self, utc: &NaiveDateTime) -> Self::Offset

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

fn offset_from_utc_date(&self, utc: &NaiveDate) -> Self::Offset

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

fn offset_from_local_date(&self, local: &NaiveDate) -> LocalResult<Self::Offset>

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

fn offset_from_local_datetime( &self, local: &NaiveDateTime, ) -> LocalResult<Self::Offset>

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

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

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

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

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

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).
