How to validate array length with io-ts?

问题 I am working on an io-ts validation where I would like to validate the list length (it has to be between min and max). I am wondering if there's a way to achieve this behavior since it could come quite handy at runtime for API endpoint validation. What I have so far is interface IMinMaxArray { readonly minMaxArray: unique symbol // use `unique symbol` here to ensure uniqueness across modules / packages } const minMaxArray = (min: number, max: number) => t.brand( t.array, (n: Array): n is t

Python Datetime: All Items From Yesterday

夙愿已清 提交于 2021-02-20 19:26:26
问题 In Python, if I wanted to do a check for all items from yesterday would I do something like: from datetime import datetime, timedelta if datetime.datetime.today() - timedelta(days=2) < item_to_check < datetime.datetime.today(): Would this pull all items from yesterday and is this the best way to do it? 回答1: I'd try something easier ;-) from datetime import date, timedelta yesterday = date.today() - timedelta(days=1) if item_to_check.date() == yesterday: # yup! Note that your: item_to_check <

Collapsing a discriminated union - derive an umbrella type with all possible key-value combinations from the union

北城以北 提交于 2021-02-20 19:23:52
问题 I have a discriminated union, for example: type Union = { a: "foo", b: string, c: number } | {a: "bar", b: boolean } I need to derive a type that includes all potential properties, assigned with types that may be found on any member of Union , even if only defined on some - in my example: type CollapsedUnion = { a: "foo" | "bar", b: string | boolean, c: number | undefined } How can I make a generic that derives such collapsed unions? I need a generic that supports unions of any size. Similar

问题 I have an application running in C#.Netcore and C++ windows application. I achieved interoperability between C# & C++ using SWIG. But I am not able to achieve Callback functionality from C++ to C#. Also I tried by passing function pointer from C# to C++. But it also failed My Intention is to achieve callback by By passing a C# function pointer to C++ and call that function pointer when needed so that C# function will be executed.

Use Gradle function from other gradle file

こ雲淡風輕ζ 提交于 2021-02-20 19:23:31
问题 I want to split my 300 lines build.gradle logically into multiple build files to make it easier to maintain and extend. As I've noticed, it is possible to split gradle tasks into multiple files and use them with: apply from: "myGradleFile" With this approach I sadly have no access to functions , defined in the second build script. Is it also possible to split Gradle functions into multiple files? Example: Let's say I have my default build.gradle with a Task which uses a function task
