Struct block2::RcBlock

source · 
pub struct RcBlock<A, R> { /* private fields */ }
Expand description

A reference-counted Objective-C block.

Implementations§

source§

impl<A, R> RcBlock<A, R>

source

pub unsafe fn new(ptr: *mut Block<A, R>) -> Self

Construct an RcBlock for the given block without copying it. The caller must ensure the block has a +1 reference count.

Safety

The given pointer must point to a valid Block and must have a +1 reference count or it will be overreleased when the RcBlock is dropped.

source

pub unsafe fn copy(ptr: *mut Block<A, R>) -> Self

Constructs an RcBlock by copying the given block.

Safety

The given pointer must point to a valid Block.

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

source

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.
