Expand description

A trait for creating allocator callbacks for PhysX.

Reporting the name, file and line is not enabled by default. Use Foundation::set_report_allocation_names to toggle this on or off.

Required Methods§

source

unsafe extern "C" fn allocate( size: u64, name: *const c_void, file: *const c_void, line: u32, user_data: *const c_void ) -> *mut c_void

Safety

Allocations must be aligned 16. This should not panic, since it is called in an FFI context and unwinding across the FFI barrier is UB.

source

unsafe extern "C" fn deallocate( ptr: *const c_void, user_data: *const c_void )

Safety

Must not panic.

Provided Methods§

source

unsafe fn into_px(self) -> *mut PxAllocatorCallback

Safety

Do not override this method.
