Struct block::ConcreteBlock

#[repr(C)]
pub struct ConcreteBlock<A, R, F> { /* fields omitted */ }

An Objective-C block whose size is known at compile time and may be constructed on the stack.

Methods

impl<A, R, F> ConcreteBlock<A, R, F> where
    A: BlockArguments,
    F: IntoConcreteBlock<A, Ret = R>, 

fn new(closure: F) -> Self

Constructs a ConcreteBlock with the given closure. When the block is called, it will return the value that results from calling the closure.

impl<A, R, F> ConcreteBlock<A, R, F> where
    F: 'static, 

fn copy(self) -> RcBlock<A, R>

Copy self onto the heap as an RcBlock.

Methods from Deref<Target = Block<A, R>>

unsafe fn call(&self, args: A) -> R

Call self with the given arguments.

Unsafe because this invokes foreign code that the caller must verify doesn't violate any of Rust's safety rules. For example, if this block is shared with multiple references, the caller must ensure that calling it will not cause a data race.

Trait Implementations

impl<A, R, F> Clone for ConcreteBlock<A, R, F> where
    F: Clone, 

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A, R, F> Deref for ConcreteBlock<A, R, F>

type Target = Block<A, R>

The resulting type after dereferencing

fn deref(&self) -> &Block<A, R>

The method called to dereference a value

impl<A, R, F> DerefMut for ConcreteBlock<A, R, F>

fn deref_mut(&mut self) -> &mut Block<A, R>

The method called to mutably dereference a value
