This question already has an answer here: How do I create a heterogeneous collection of objects? (1 answer) Closed 3 days ago. I have a trait Input that adds a to_custom_bytes() method to Strings and u64s. trait Input { fn to_custom_bytes(&self) -> Vec<u8>; } impl Input for u64 { fn to_custom_bytes(&self) -> Vec<u8> { self.to_le_bytes().to_vec() […]

I’m trying to implement a trait for Display and Debug traits, but rust responds with conflicting implementations.

I’m trying to implement a trait for Display and Debug traits, but rust responds with conflicting implementations.

Say that I have the following trait:

Consider a trait which requires a certain cleanup method to be implemented and also ensure that this cleanup is actually performed when an instance is dropped. That we can write something like this:

Consider the following code:

I would like a trait X to implement the Display trait so that it’s available for all structs that implement X.

Studying Rust and Kotlin at the moment, I wonder whether something as neat as Kotlin’s Scope functions (let, apply, run, etc.) could be / are implemented in Rust?

I have a trait with an associated type Value, and two methods. One returns &Self::Value and the other receives Self::Value. This trait is implemented for several types, but I want to implement it for one type in particular where type Value = Option<...>. This creates a problem, as demonstrated below (playground):
