Implementations

impl TransitionRule

pub(super) fn from_tz_string( tz_string: &[u8], use_string_extensions: bool, ) -> Result<Self, Error>

Parse a POSIX TZ string containing a time zone description, as described in the POSIX documentation of the TZ environment variable.

TZ string extensions from RFC 8536 may be used.

pub(super) fn find_local_time_type( &self, unix_time: i64, ) -> Result<&LocalTimeType, Error>

Find the local time type associated to the transition rule at the specified Unix time in seconds

pub(super) fn find_local_time_type_from_local( &self, local_time: i64, year: i32, ) -> Result<MappedLocalTime<LocalTimeType>, Error>

Find the local time type associated to the transition rule at the specified Unix time in seconds

Trait Implementations

impl Clone for TransitionRule

fn clone(&self) -> TransitionRule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransitionRule

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

Formats the value using the given formatter.

impl From<AlternateTime> for TransitionRule

fn from(inner: AlternateTime) -> Self

Converts to this type from the input type.

impl From<LocalTimeType> for TransitionRule

fn from(inner: LocalTimeType) -> Self

Converts to this type from the input type.

impl PartialEq for TransitionRule

fn eq(&self, other: &TransitionRule) -> 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.
