Struct CFTimeZone 

pub struct CFTimeZone(/* private fields */);

Safe wrapper around a retained Core Foundation CFTimeZone reference.

Implementations

impl CFTimeZone

pub unsafe fn from_raw(ptr: *mut c_void) -> Option<Self>

Adopts a +1 retained CFTimeZone pointer and returns None for null.

Safety

A non-null ptr must be a live CFTimeZone pointer of the exact dynamic type carrying one retain transferred to this wrapper. The caller must not release or separately adopt that transferred retain.

pub unsafe fn from_raw_borrowed(ptr: *mut c_void) -> Option<Self>

Retains a +0 borrowed CFTimeZone pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFTimeZone pointer of the exact dynamic type for the duration of the retain call.

pub const fn as_ptr(&self) -> *mut c_void

Borrows the raw +0 Core Foundation pointer while self remains alive.

pub fn type_id() -> usize

Returns the Core Foundation type ID for CFTimeZone.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFTimeZone

pub fn current() -> Self

Current system time zone.

pub fn new(name: &str) -> Self

Create a time zone by name, for example UTC.

pub fn name(&self) -> CFString

Time zone name.

pub fn seconds_from_gmt(&self, date: &CFDate) -> i32

Offset from GMT in seconds for the supplied date.
