I need a function which will cast Map to Map<String, List<Int>> Currently I use unsafe "as" but I receive a fair warning about it. I want to fix it. For list part I was able to implement function inline fun <reified T : Any> List<*>.checkItemsAre(): List<T> { return this.filterIsInstance<T>().takeIf { it.size == this.size } ?:… Read More How to safety cast raw Map to Map<String, List<Int>> in Kotlin?
In my tests I want to replace the setTimeout method so that the tests run fast. Originally I had the equivalent piece of code that used "any"… But of course eslint etc bleats. I now have this piece of code which at last does not have any in it. let defaultTimeout: typeof globalThis.setTimeout; beforeEach(() =>… Read More How do I replace the setTimeout method in a typesafe manner?
I have made the following definition of a spline data structure: #[derive(Clone, Debug)] pub struct BSpline { knots: Vec<f32>, control_points: Vec<Vec3>, /// Internal helper variable. Used to optimize repetetitive samplings on close /// $t$ values. last_t_index: usize, order: usize, } impl BSpline { pub fn sample(&self, t: f32) -> Vec3 { debug_assert!(self.control_points.len() >= self.order); let… Read More More sound approach to designing a spline functor?
I have a routesList that I use in the app-routing.module of Angular The type of the routesList is: type routesList = { [key: string]: { path: string; title: string; component: Type<Component>; }; }; The current list that is being exported is: export const routesList: routesList = { home: { path: ”, title: ‘Curation Console’, component:… Read More Angular type of Components
Let’s have the following two interfaces: interface A { foo: string; bar: number; } interface B { foo: string; } How can I type-safely convert an object that conforms to A to one that conforms to B? This doesn’t work: const a = { foo: "baz", bar: 42 } const b: B = {…a} delete… Read More How to type-safely remove a property from a TypeScript type
How can I achieve typesafety for this converting case? I’m mapping over the palette and convert any object with entries to key value pairs, like tailwindcss does for their color configuration. However the type of colors don’t contain the gray colors instead only the non converted entry keys as type. const palette = { white:… Read More How can I correctly type this object converting?
I have sort of an open question, but I have tried quite a few solution and none of them are really satisfactory I would say so hopefully someone here has an idea of whether I am missing some solution. As you can see below I have a class ExposedMethod, which defines a method that can… Read More Encapsulating Parameters and Arguments in classes
