• rangep must be a valid pointer.
• value_ptr must be a valid pointer.

pub unsafe fn set_property( &self, key: Option<&CFNumberFormatterKey>, value: Option<&CFType>, )

Safety

• key might not allow None.
• value should be of the correct type.
• value might not allow None.

pub unsafe fn property( &self, key: Option<&CFNumberFormatterKey>, ) -> Option<CFRetained<CFType>>

Safety

key might not allow None.

impl CFNumberFormatter

pub unsafe fn decimal_info_for_currency_code( currency_code: Option<&CFString>, default_fraction_digits: *mut i32, rounding_increment: *mut c_double, ) -> bool

Safety

• currency_code might not allow None.
• default_fraction_digits must be a valid pointer.
• rounding_increment must be a valid pointer.

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 CFNumberFormatter

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFNumberFormatter> for CFNumberFormatter

fn as_ref(&self) -> &Self

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

impl AsRef<CFType> for CFNumberFormatter

fn as_ref(&self) -> &CFType

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

impl Borrow<AnyObject> for CFNumberFormatter

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CFNumberFormatter

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CFNumberFormatter

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CFNumberFormatter

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

Formats the value using the given formatter.

impl Deref for CFNumberFormatter

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CFNumberFormatter

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 CFNumberFormatter

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CFNumberFormatter

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 RefEncode for CFNumberFormatter

const ENCODING_REF: Encoding

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

impl Type for CFNumberFormatter

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

where Self: Sized,

Increment the reference count of the receiver.
