only.sourcepub fn encoding(&self) -> Encoding
pub fn encoding(&self) -> Encoding
The Objective-C encoding of this NSNumber
.
This is guaranteed to return one of:
Encoding::Char
Encoding::UChar
Encoding::Short
Encoding::UShort
Encoding::Int
Encoding::UInt
Encoding::Long
Encoding::ULong
Encoding::LongLong
Encoding::ULongLong
Encoding::Float
Encoding::Double
§Examples
Convert an NSNumber
to/from an enumeration describing the different
number properties.
use objc2_foundation::NSNumber;
use objc2::encode::Encoding;
use objc2::rc::Retained;
// Note: `bool` would convert to either `Signed` or `Unsigned`,
// depending on platform
#[derive(Copy, Clone)]
pub enum Number {
Signed(i64),
Unsigned(u64),
Floating(f64),
}
impl Number {
fn into_nsnumber(self) -> Retained<NSNumber> {
match self {
Self::Signed(val) => NSNumber::new_i64(val),
Self::Unsigned(val) => NSNumber::new_u64(val),
Self::Floating(val) => NSNumber::new_f64(val),
}
}
}
impl From<&NSNumber> for Number {
fn from(n: &NSNumber) -> Self {
match n.encoding() {
Encoding::Char
| Encoding::Short
| Encoding::Int
| Encoding::Long
| Encoding::LongLong => Self::Signed(n.as_i64()),
Encoding::UChar
| Encoding::UShort
| Encoding::UInt
| Encoding::ULong
| Encoding::ULongLong => Self::Unsigned(n.as_u64()),
Encoding::Float

sourcepub unsafe fn get<T: 'static + Copy + Encode>(&self) -> T
pub unsafe fn get<T: 'static + Copy + Encode>(&self) -> T
Retrieve the data contained in the NSValue
.
Note that this is broken on GNUStep for some types, see gnustep/libs-base#216.
§Safety
The type of T
must be what the NSValue actually stores, and any
safety invariants that the value has must be upheld.
Note that it may be enough, although is not always, to check whether
contains_encoding
returns true
. For example, NonNull<T>
have
the same encoding as *const T
, but NonNull<T>
is clearly not
safe to return from this function even if you’ve checked the encoding
beforehand.
§Examples
Store a pointer in NSValue
, and retrieve it again afterwards.
use std::ffi::c_void;
use std::ptr;
use objc2_foundation::NSValue;
let val = NSValue::new::<*const c_void>(ptr::null());
// SAFETY: The value was just created with a pointer
let res = unsafe { val.get::<*const c_void>() };
assert!(res.is_null());

Methods from Deref<Target = NSObject>§
sourcepub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
Handle messages the object doesn’t recognize.
See Apple’s documentation for details.
Methods from Deref<Target = AnyObject>§
sourcepub fn class(&self) -> &'static AnyClass
pub fn class(&self) -> &'static AnyClass
Dynamically find the class of this object.
§Example
Check that an instance of NSObject
has the precise class NSObject
.
use objc2::ClassType;
use objc2::runtime::NSObject;
let obj = NSObject::new();
assert_eq!(obj.class(), NSObject::class());
sourcepub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere

👎Deprecated: this is difficult to use correctly, use Ivar::load
instead.
pub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
Ivar::load
instead.Use Ivar::load
instead.
§Safety
The object must have an instance variable with the given name, and it
must be of type T
.
See Ivar::load_ptr
for details surrounding this.
sourcepub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut Twhere
T: Encode,
👎Deprecated: this is difficult to use correctly, use Ivar::load_mut
instead.
pub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut Twhere
T: Encode,
Ivar::load_mut
instead.Use Ivar::load_mut
instead.
§Safety
The object must have an instance variable with the given name, and it
must be of type T
.

for details surrounding this.
