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 […]
We write a program using Rust to take user input and display the result back to the user. This tutorial shows how to get the input, parse it, convert it to/from a string and then display it. We begin with the io module: “The std::io module contains a number of common things you’ll need when doing input […]
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 […]
Let’s look at how to use a “getter”method in Rust Programming Language. If you’ve used a getter method with object oriented languages you’ll be familiar with accessing data from an instance of a class. The method we use will allow us to get the car name string aka “cname” from the instance of the car […]
Define a struct, think of it like a Python dictionary, there is an option to include methods as well but we’ll leave that for another day. Note : ” If the struct also contains heap based data types such as a STRING, then the STRING pointer and associated information are put on the stack with the rest of the […]
In this example we access a string (stored on the heap) and modify it using the & to borrow it and update it. Integers can be modified on the stack, but a String is an Array of unknown length so it has to live on the heap… Get the Rust Example Code:
