Struct objc2_foundation::NSMutableData

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

This is the Objective-C equivalent of a Vec containing u8.

See Apple’s documentation.

Implementations

impl NSMutableData

pub fn class() -> &'static Class

impl NSMutableData

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

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

pub fn from_data(data: &NSData) -> Id<Self, Owned>

pub fn with_capacity(capacity: usize) -> Id<Self, Owned>

impl NSMutableData

Mutation methods

pub fn bytes_mut(&mut self) -> &mut [u8]

pub fn set_len(&mut self, len: usize)

Expands with zeroes, or truncates the buffer.

pub fn extend_from_slice(&mut self, bytes: &[u8])

pub fn push(&mut self, byte: u8)

pub fn replace_range(&mut self, range: Range<usize>, bytes: &[u8])

pub fn set_bytes(&mut self, bytes: &[u8])

Methods from Deref<Target = NSData>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

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.
