Struct Value 

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

An Objective-C value object.

C++ equivalent: NS::Value

Implementations

impl Value

pub fn value(value: *const c_void, obj_c_type: *const c_char) -> Option<Self>

Create a value from bytes and type encoding.

C++ equivalent: static Value* value(const void* pValue, const char* pType)

pub fn value_with_pointer(pointer: *const c_void) -> Option<Self>

Create a value from a pointer.

C++ equivalent: static Value* value(const void* pPointer)

pub fn alloc() -> Option<Self>

Allocate a new value.

C++ equivalent: static Value* alloc()

pub fn init_with_bytes( &self, value: *const c_void, obj_c_type: *const c_char, ) -> Option<Self>

Initialize with bytes and type encoding.

C++ equivalent: Value* init(const void* pValue, const char* pType)

pub fn init_with_coder(&self, coder: *const c_void) -> Option<Self>

Initialize with a coder.

C++ equivalent: Value* init(const class Coder* pCoder)

pub fn get_value(&self, value: *mut c_void, size: UInteger)

Get the value bytes.

C++ equivalent: void getValue(void* pValue, UInteger size) const

pub fn objc_type(&self) -> *const c_char

Get the Objective-C type encoding.

C++ equivalent: const char* objCType() const

pub fn is_equal_to_value(&self, value: &Value) -> bool

Check if equal to another value.

C++ equivalent: bool isEqualToValue(Value* pValue) const

pub fn pointer_value(&self) -> *mut c_void

Get the pointer value.

C++ equivalent: void* pointerValue() const

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

Create a Value from a raw pointer.

Safety

The pointer must be a valid Objective-C NSValue object.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copying for Value

fn copy(&self) -> Option<Self>

Create a copy of this object.

impl Referencing for Value

fn as_ptr(&self) -> *const c_void

Get the raw pointer to the Objective-C object.

fn as_mut_ptr(&self) -> *mut c_void

Get the raw mutable pointer to the Objective-C object.

fn retain(&self) -> Self

where Self: Clone,

Retain the object, incrementing its reference count.

fn release(&self)

Release the object, decrementing its reference count.

fn autorelease(&self) -> Self

where Self: Clone,

Autorelease the object.

fn retain_count(&self) -> UInteger

Get the retain count of the object.

impl Send for Value
