Type Alias HurrayReleaseCallback 

pub type HurrayReleaseCallback = Option<unsafe extern "C" fn(*mut c_void, *mut c_void)>;

Optional release callback invoked by hurray_buffer_destroy.

The first argument is the data pointer passed to hurray_buffer_from_ptr. The second argument is the release_context pointer passed to the same function. Both arguments carry the exact values provided at construction time.

Implementations MUST NOT call back into the Hurray C ABI from within this callback; doing so may cause deadlocks or use-after-free.
