Implementations

impl CFDate

pub fn from_system_time(time: &SystemTime) -> CFRetained<Self>

Available on crate feature std only.

Create a CFDate from a SystemTime.

Nanosecond precision may be lost.

pub fn to_system_time(&self) -> Option<SystemTime>

Available on crate feature std only.

Try to construct a SystemTime from the CFDate.

Nanosecond precision may be lost.

Returns None if the CFDate is too large to fit inside SystemTime.

impl CFDate

pub fn new( allocator: Option<&CFAllocator>, at: CFAbsoluteTime, ) -> Option<CFRetained<CFDate>>

pub fn absolute_time(self: &CFDate) -> CFAbsoluteTime

pub fn time_interval_since_date( self: &CFDate, other_date: Option<&CFDate>, ) -> CFTimeInterval

pub unsafe fn compare( self: &CFDate, other_date: Option<&CFDate>, context: *mut c_void, ) -> CFComparisonResult

Methods from Deref<Target = CFType>

pub fn downcast_ref<T: ConcreteType>(&self) -> Option<&T>

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

pub fn retain_count(&self) -> usize

Get the reference count of the object.

This function may be useful for debugging. You normally do not use this function otherwise.

Beware that some things (like CFNumbers, small CFStrings etc.) may not have a normal retain count for optimization purposes, and can return usize::MAX in that case.

Trait Implementations

impl AsRef<AnyObject> for CFDate

fn as_ref(&self) -> &AnyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFDate> for CFDate

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFType> for CFDate

fn as_ref(&self) -> &CFType

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<AnyObject> for CFDate

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CFDate

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFDate

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFDate

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

Formats the value using the given formatter.

impl Deref for CFDate

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for CFDate

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for CFDate

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl Ord for CFDate

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CFDate

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

impl PartialOrd for CFDate

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for CFDate

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.

impl Type for CFDate

fn retain(&self) -> CFRetained<Self>

where Self: Sized,

Increment the reference count of the receiver.

Helper for easier transition from the core-foundation crate.

unsafe fn wrap_under_create_rule(ptr: *const Self) -> CFRetained<Self>

where Self: Sized,

👎Deprecated: use CFRetained::from_raw

Helper for easier transition from the core-foundation crate.
