Represent the rules defining a TimeZone.

Fields

timecnt: i32

The count of time transitions.

typecnt: i32

The count of time type infos.

charcnt: i32

The count of chars.

goback: bool

Used to control the rule that should apply when a specified time is out of any rules in the past.

goahead: bool

Used to control the rule that should apply when a specified time is out of any rules in the future.

ats: [Time; 1000]

Time transition timepoints.

types: [u8; 1000]

Time transition types.

ttis: [TimeTypeInfo; 128]

Time type infos.

chars: [u8; 512]

The chars.

default_type: i32

The index of the default type (usually zero).

reserved: [u8; 4804]

Reserved / Unused space.

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.
