Implementations

impl TimeZoneRule[−]

pub fn from_bytes(buffer: &[u8]) -> &Self[−]

Load the given timezones rules from a given slice contains an actual TimeZoneRule.

Panic:

This function panic if the given buffer is either too short or not aligned

pub fn from_mut_bytes(buffer: &mut [u8]) -> &mut Self[−]

Load the given timezones rules from a given slice contains an actual TimeZoneRule.

Panic:

This function panic if the given buffer is either too short or not aligned

pub fn load_rules(
    &mut self,
    input: &[u8],
    temp_rules: &mut TimeZoneRule
) -> TimeZoneResult<()>[−]

Load the given timezones rules from a given slice containing TzIf2 data and a temporary TimeZoneRule buffer.

Note:

temp_rules is used to store parsed data from the TZ String Extensions. this shouldn't be used as a standard TimeZoneRule!

pub fn to_calendar_time(&self, time: PosixTime) -> TimeZoneResult<CalendarTime>[−]

Convert a PosixTime to a CalendarTime using the current timezone.

pub fn to_posix_time(
    &self,
    calendar_time: &CalendarTimeInfo
) -> TimeZoneResult<PosixTime>[−]

Convert a CalendarTime to a PosixTime using the current timezone.
