Implementations

source

impl NSMutableDictionary

source

pub fn new() -> Self

Constructs an NSMutableDictionary and retains it.

Why mutable? It’s just easier for working with it, as they’re (mostly) interchangeable when passed around in Objective-C. We guard against mutation on our side using the standard Rust object model. You can, of course, bypass it and msg_send![] yourself, but it’d require an unsafe {} block… so you’ll know you’re in special territory then.

source

pub fn insert(&mut self, key: NSString<'_>, object: id)

Inserts an object into the backing NSMutablyDictionary.

This intentionally requires NSString be allocated ahead of time.

source

pub fn into_inner(self) -> id

Consumes and returns the underlying NSMutableDictionary.

Methods from Deref<Target = Object>

source

pub fn class(&self) -> &Class

Returns the class of self.

source

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

Returns a reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

source

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

Returns a mutable reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

source

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

Sets the value of the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.
