Struct block2::GlobalBlock

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

An Objective-C block that does not capture it’s environment.

This is effectively just a glorified function pointer, and can created and stored in static memory using the global_block macro.

If ConcreteBlock is the Fn-block equivalent, this is likewise the fn-block equivalent.

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

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

Call self with the given arguments.

Safety

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> Deref for GlobalBlock<A, R> where
    A: BlockArguments + EncodeArguments,
    R: Encode, 

type Target = Block<A, R>

The resulting type after dereferencing.

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

Dereferences the value.

impl<A, R> Send for GlobalBlock<A, R> where
