Introduction: Unlock the power of generics in Rust with this concise code example. Learn how to define and leverage generic types using the Query struct, which takes a flexible type parameter T. The accompanying meh function showcases the versatility of generics by accepting a Query<i32> instance. Discover the elegance and expressiveness of Rust’s generic programming […]
Should this compile, my initial expectation was that it would not….. In Rust, moving a value out of a Box or any other owned container is allowed, but it doesn’t invalidate the original variable (v in this case). The variable v is still in scope, and you can continue using it. However, when you print […]
I have a chat with chatGPT about Musl, static linking, libc.so.6 and dereferencing smart pointers…here is the conversation! is it possible to make a rust program that prints it’s main.rs and shows what variables live on the stack and which live on the heap? In Rust, it’s not straightforward to inspect the stack and heap […]
How to write your own library and import it from GitHub, via Cargo.toml
🟩 Rust, main.rs is typically used for the entry point of standalone executables, containing the main function. lib.rs is for library code, providing reusable functionality. When building a binary, main.rs is used; for libraries, lib.rs holds the central module.
I’ve chosen a project on GitHub to pick apart and study to learn some new code, crates and ideas. The project is : https://github.com/kyoheiu/url-shortener-axum-sled I chose it because I want to learn more about Sled as it’s recommended to be used with BDK (Bitcoin Development Kit) First, let’s have a look at Cargo.toml and see […]
In Rust, the From trait plays a crucial role in allowing the conversion of one type into another. Let’s explore this concept through a straightforward example involving the conversion of lengths from feet to meters. Struct Definitions Here, we have two structs, Feet and Meters, each representing a length in a different unit. From Trait […]
Here we continue trying out BDK and learning to use it with Rust : By the end of this article our code will do the following : During testing I had this “Dust” error, so let’s just cover that first… BDK – Error: OutputBelowDustLimit(0) When testing on Testnet you may come across errors with the […]
Error handling is a crucial aspect of writing robust and reliable code. In Rust, two common types for representing potential errors are Option and Result. While both are useful, there are situations where using Result provides a more expressive and idiomatic way to handle errors, especially when dealing with functions that can fail due to […]
