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 […]
Bitcoin Script is a powerful and unique scripting language at the heart of the Bitcoin blockchain, defining the rules governing transaction execution. Designed by Satoshi Nakamoto, it enables users to create complex, programmable transactions, unlocking a realm of possibilities beyond simple peer-to-peer transfers. Let’s look at the basics of how it works… Successful Basic Script […]
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 […]
