Implementing a when() trait to perform conditional calls on widget builders (Rust)
I created a trait that allows me to chain conditional transformations. Extension methods are available in many languages (Rust, C#, Swift, Scala, Kotlin, ...), but me (coming from PHP and Java) only learned about them recently and it opened up a whole new world for me. For example, in Laravel (PHP), there are some types that ship with a when() helper. However, it is not possible to add such methods from the outside,...

Mock the File System
It happens quite often that our applications need to interact with the file system. As a result, some components inevitably depend on it. When we test such code, we face a choice: mock the file system, or test against the real one? There are several opposing views on this. Most developers avoid using the file system in unit tests. Tests that touch the disk are usually treated as an antiβpattern because they are slow...
