tsafe VS eslint-plugin-total-functions

Hello, This is a use case for tsafe, a utility that let you make assertions on types.

Zod is a solution for generating validators. I used to be reluctant to use it because I like to declare my types with the TypeScript syntax. I am not satisfied by getting the type inferred from the validator. The solution I found is to use tsafe, a utility that enables to make sure that two types are equals. With this solution you'll have to declare your type twice, once with the TypeScript syntax and once when declaring your zod parser but you are garentied that if you update your type and forget to update the corresponding zod parser your app won't build.

Hi, Checkout tsafe. It enables to test types definition. Checkout this GIF in particular. Let's say for example that we have an objectFromEntries function and we want to test it typewise, we can do: ```typescript import { objectEntries } from "../myObjectFromEntries"; import { assert } from "tsafe";

`Object.fromEntries()`, `Object.entries()` and `Object.keys()` are barely usable when in a TypeScript codebase because their return type are very vague. [tsafe](https://github.com/garronej/tsafe) features three new utilities: [objectFromEntries()](https://docs.tsafe.dev/objectfromentries), [objectEntries()](https://docs.tsafe.dev/objectentries) and [objectKeys()](https://docs.tsafe.dev/objectkeys), functionally equivalent to their built-in counterpart but featuring much better return types.

Three GIFs to convince you that you need tsafe in your life:

There’s also eslint-plugin-total-functions, which includes the rule total-functions/no-unsafe-readonly-mutable-assignment which warns when a readonly type is assigned to or passed as an argument to a function taking a mutable type.
