Struct CFNumber 

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

Safe wrapper around a retained Core Foundation CFNumber reference.

Implementations

impl CFNumber

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

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

Safety

A non-null ptr must be a live CFNumber 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 CFNumber pointer and returns an owned wrapper.

Safety

A non-null ptr must be a live CFNumber 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 CFNumber.

pub fn into_cf_type(self) -> CFType

Consumes this wrapper and returns the erased CFType.

impl CFNumber

pub fn from_i64(value: i64) -> Self

Create an integer number.

pub fn from_u64(value: u64) -> Self

Create an unsigned integer number.

pub fn from_f64(value: f64) -> Self

Create a floating-point number.

pub fn to_i64(&self) -> Option<i64>

Convert to i64 if representable.

pub fn to_u64(&self) -> Option<u64>

Convert to u64 if representable.

pub fn to_f64(&self) -> Option<f64>

Convert to f64 if representable.

pub fn is_float_type(&self) -> bool

Whether the number was created from a floating-point representation.
