One of the frustrations with learning from some text books is that they set vague exercises at the end of a chapter without being explicit in the nature of the task and therefore no solution either…. For example “Write a function to convert text to ascii” Codewars Replace With Alphabet Position I’ve started to use […]
This is an initial example of Traits in Rust. There are more complicated examples than this but to get started this is a nice way to understand how to create a Trait and how to use it. Try the code: Try this code in Rust Playground : https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=6e50061eff5ac64ceed63bd55ff767e6 Note how the definition part on line […]
Using secp256k1 Rust bindings for Pieter Wuille’s secp256k1 library, which is used for fast and accurate manipulation of ECDSA signatures on the secp256k1 curve. Such signatures are used extensively by the Bitcoin network and its derivatives. secp256k1 This article shows the code used to create a public/private keypair using secp.generate_keypair in Rust. Also, make sure […]
In Rust rather than have to create separate structs to accept variables with different data types you can use a generic struct, eg accepting a float…or an integer. Without this, you would need to make one struct to accept u8 and one struct to f64 (if they are the 2 data types you desire). Let’s […]
