Attribute Macro blockz_derive::singleton_fn

#[singleton_fn]

Modify a method on a type that implements the Singleton trait.

The modified method becomes a function that will use the underlying singleton.

The input function must have the following properties:

• the first argument must be a reference receiver (&self or &mut self)
• function arguments identifiers must not conflict with other identifiers from the function body (such as other function names in function calls, struct fields etc)
• references are not allowed (use Box<T> or Arc<T> instead)
