impl ContextRef
sourcepub unsafe fn from_ptr<'a>(ptr: *mut cubeb) -> &'a ContextRef
 
pub unsafe fn from_ptr<'a>(ptr: *mut cubeb) -> &'a ContextRef
§Safety
This function is unsafe because it dereferences the given ptr pointer.
The caller should ensure that pointer is valid.
sourcepub unsafe fn from_ptr_mut<'a>(ptr: *mut cubeb) -> &'a mut ContextRef
 
pub unsafe fn from_ptr_mut<'a>(ptr: *mut cubeb) -> &'a mut ContextRef
§Safety
This function is unsafe because it dereferences the given ptr pointer.
The caller should ensure that pointer is valid.

§Safety
This function is unsafe because it dereferences the given data_callback, state_callback, and user_ptr pointers.
The caller should ensure those pointers are valid.

§Safety
This function is unsafe because it dereferences the given callback and  user_ptr pointers.
The caller should ensure those pointers are valid.
