    fn unwrap(self) -> &'static mut Self::Type
    where

}

An owned singleton: a proxy (handle) for a static mut variable

Required Associated Types

type Type

Required Methods

unsafe fn new() -> Self

Creates a new singleton

Unsafety

It’s UB to create more than one instance of this singleton

fn get() -> *mut Self::Type

Returns a pointer to the static mut variable behind this proxy

Provided Methods

fn unwrap(self) -> &'static mut Self::Typewhere
    Self: Sized,

Consumes this singleton and returns a &'static mut reference to the variable behind it
