Enum TimeZone 

pub enum TimeZone {
    Iana(TimeZoneId),
    FixedOffset(TimeZoneOffset),
}

A time zone represented by either an IANA-shaped identifier or a fixed offset.

Variants

Iana(TimeZoneId)

An IANA-shaped time zone identifier.

FixedOffset(TimeZoneOffset)

A fixed UTC offset.

Implementations

impl TimeZone

pub fn new(input: &str) -> Option<Self>

Parses a time zone.

pub fn try_new(input: &str) -> Result<Self, TimeZoneParseError>

Parses a time zone with diagnostic errors.

Errors

Returns TimeZoneParseError when the input is empty, contains whitespace, is an invalid fixed offset, or is not an IANA-shaped identifier.

pub const fn iana(identifier: TimeZoneId) -> Self

Returns an IANA time zone value.

pub const fn fixed_offset(offset: TimeZoneOffset) -> Self

Returns a fixed-offset time zone value.

pub const fn as_time_zone_id(&self) -> Option<&TimeZoneId>

Returns the IANA identifier when this time zone is identifier-based.

pub const fn offset(&self) -> Option<TimeZoneOffset>

Returns the fixed offset when this time zone is offset-based.

pub const fn is_iana(&self) -> bool

Returns true when this time zone is an IANA-shaped identifier.

pub const fn is_fixed_offset(&self) -> bool

Returns true when this time zone is a fixed offset.

Trait Implementations

impl Clone for TimeZone

fn clone(&self) -> TimeZone

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeZone

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

Formats the value using the given formatter.

impl Display for TimeZone

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

Formats the value using the given formatter.

impl Hash for TimeZone

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 Ord for TimeZone

fn cmp(&self, other: &TimeZone) -> 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 PartialEq for TimeZone

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

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