1) The owner of a value is a variable
2) At any time, only a single owner is allowed
3) The value is lost once the owner goes out of scope
#rust #ownership #rs
function monadConstructor() {
return function unit(value) {
let monad = Object.create(null);
monad.bind = function (fn) {
return fn(value);
};
return monad;
}
}
