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 […]
I demo ECDSA public/private keys with digital signatures using Streamlit… The private key gets generated, and stays private. The public key is given to the person who want’s to verify the message. Using the public key plus the signed message they can be sure that the only the owner of the matching private key signed […]
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 […]
Partially Signed Bitcoin Transactions (PSBTs) are a standardized way of representing a Bitcoin transaction and its signatures, allowing different parties to collaborate in creating a transaction without sharing private keys. PSBTs are often used in multi-signature setups or with hardware wallets. In this article we’ll discover more about how Bitcoin Script can be created with […]
Taproot” is an upgrade to the Bitcoin network that aims to enhance privacy, improve scripting flexibility, and optimize the use of resources. Let me break it down into simpler terms: In summary, Taproot is like an upgrade for Bitcoin that makes transactions more private, scripting more flexible, and resource usage more efficient. It’s a step […]
