Struct cxx_qt_lib::QTimeZone

#[repr(C)]
pub struct QTimeZone { /* private fields */ }

The QTimeZone class converts between UTC and local time in a specific time zone.

Implementations

impl QTimeZone

pub fn abbreviation(&self, atDateTime: &QDateTime) -> QString

Returns the time zone abbreviation at the given atDateTime. The abbreviation may change depending on DST or even historical events.

impl QTimeZone

pub fn comment(&self) -> QString

Returns any comment for the time zone.

impl QTimeZone

pub fn daylight_time_offset(&self, atDateTime: &QDateTime) -> i32

Returns the daylight-saving time offset at the given atDateTime, i.e. the number of seconds to add to the standard time offset to obtain the local daylight-saving time.

impl QTimeZone

pub fn has_daylight_time(&self) -> bool

Returns true if the time zone has practiced daylight-saving at any time.

impl QTimeZone

pub fn has_transitions(&self) -> bool

Returns true if the system backend supports obtaining transitions.

impl QTimeZone

pub fn id(&self) -> QByteArray

Returns the IANA ID for the time zone.

impl QTimeZone

pub fn is_daylight_time(&self, atDateTime: &QDateTime) -> bool

Returns true if daylight-saving was in effect at the given atDateTime.

impl QTimeZone

pub fn is_valid(&self) -> bool

Returns true if this time zone is valid.

impl QTimeZone

pub fn offset_from_utc(&self, atDateTime: &QDateTime) -> i32

Returns the total effective offset at the given atDateTime, i.e. the number of seconds to add to UTC to obtain the local time. This includes any DST offset that may be in effect, i.e. it is the sum of standardTimeOffset() and daylightTimeOffset() for the given datetime.

impl QTimeZone

pub fn standard_time_offset(&self, atDateTime: &QDateTime) -> i32

Returns the standard time offset at the given atDateTime, i.e. the number of seconds to add to UTC to obtain the local Standard Time. This excludes any DST offset that may be in effect.

impl QTimeZone

pub fn available_time_zone_ids() -> QList<QByteArray>

Returns a list of all available IANA time zone IDs on this system.

pub fn from_offset_seconds(offset_seconds: i32) -> UniquePtr<Self>

Creates an instance of a time zone with the requested Offset from UTC of offsetSeconds.

pub fn from_iana(iana_id: &QByteArray) -> UniquePtr<Self>

Creates an instance of the requested time zone ianaId.

pub fn new() -> UniquePtr<Self>

Create a null/invalid time zone instance.

pub fn system_time_zone() -> UniquePtr<Self>

Returns a QTimeZone object that refers to the local system time, as specified by systemTimeZoneId().

pub fn system_time_zone_id() -> QByteArray

Returns the current system time zone IANA ID.

pub fn to_owned(&self) -> UniquePtr<Self>

Copy constructor, create a copy of the QTimeZone.

pub fn utc() -> UniquePtr<Self>

Returns a QTimeZone object that refers to UTC (Universal Time Coordinated).

Trait Implementations

impl Debug for QTimeZone

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

Formats the value using the given formatter.

impl Display for QTimeZone

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

Formats the value using the given formatter.

impl ExternType for QTimeZone

type Kind = Opaque

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

A type-level representation of the type’s C++ namespace and type name.

impl PartialEq for QTimeZone

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
