Struct objc2_foundation::NSData

#[repr(C)]
pub struct NSData { /* private fields */ }

A static byte buffer in memory.

This is similar to a slice of u8.

See Apple’s documentation.

Implementations

impl NSData

pub fn class() -> &'static Class

impl NSData

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn bytes(&self) -> &[u8]

pub fn with_bytes(bytes: &[u8]) -> Id<Self, Shared>

pub fn from_vec(bytes: Vec<u8>) -> Id<Self, Shared>

Methods from Deref<Target = NSObject>

pub fn hash_code(&self) -> usize

pub fn is_equal(&self, other: &NSObject) -> bool

pub fn description(&self) -> Id<NSString, Shared>

pub fn is_kind_of(&self, cls: &Class) -> bool

Methods from Deref<Target = Object>

pub fn class(&self) -> &Class

Dynamically find the class of this object.

pub unsafe fn ivar<T>(&self, name: &str) -> &T where
    T: Encode, 

Returns a shared reference to the ivar with the given name.

Panics

Panics if the object has no ivar with the given name, or the type encoding of the ivar differs from the type encoding of T.

Safety

The caller must ensure that the ivar is actually of type T.

Library implementors should expose a safe interface to the ivar.

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T where
    T: Encode, 

👎 Deprecated:

Use Object::ivar instead.

Use ivar instead.

Safety

Same as ivar.

pub unsafe fn ivar_mut<T>(&mut self, name: &str) -> &mut T where
    T: Encode, 

Returns a mutable reference to the ivar with the given name.

Panics

Panics if the object has no ivar with the given name, or the type encoding of the ivar differs from the type encoding of T.

Safety

The caller must ensure that the ivar is actually of type T.

Library implementors should expose a safe interface to the ivar.

pub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut T where
    T: Encode, 

👎 Deprecated:

Use Object::ivar_mut instead.

Use ivar_mut instead.

Safety

Same as ivar_mut.

pub unsafe fn set_ivar<T>(&mut self, name: &str, value: T) where
    T: Encode, 

Sets the value of the ivar with the given name.

Panics

Panics if the object has no ivar with the given name, or the type encoding of the ivar differs from the type encoding of T.

Safety

The caller must ensure that the ivar is actually of type T.

Library implementors should expose a safe interface to the ivar.
