How to read and write YAML in Rust with Serde
In this article, we will learn how to read and write YAML files in Rust with the Serde framework. Being able to read YAML files enables you to, for example, use YAML files as configuration files for your projects. This article will not be very in-depth, just a simple example of how to read and write YAML data from a file. The full code for this article can be found on my GitHub. Prerequisites Some understanding of Rust is required. Familiarity with YAML and its structure is also a plus. Creating the project and dependencies Let’s create the project and…

Binance API crypto transaction with Rust: how to
In this article, we are going to learn how to do a buy transaction of crypto with the Binance API. As usual, we will be using the rust programming language. The full project’s repository can be found on my GitHub. I also have another article related to the Binance API: Easily connect to Binance WebSocket streams with Rust Prerequisites To be able to follow this article you should have: Rust installed Some familiarity with Rust and programming against a REST API is helpful. A Binance account. Verification on your Binance account so that you can create an API key. To…
Crypto triangle arbitrage dashboard, part 3: how to add logging
Logging to a storage medium is useful for troubleshooting and analysis when any note-worthy events have occurred. In this article, we will do a quick update to the code base we created in part 1: Crypto triangle arbitrage dashboard: how to, part 1 to add logging to a file for our rust backend. We will add logging to stdout and a file making use of the log4rs crate. For details on how to use log4rs please check out my article about basic file logging with log4rs. Prerequisites Since we are updating the existing code base for the crypto triangle arbitrage…
Basic how to log to a file in Rust with log4rs
In this article, we will take look at how you can use and configure log4rs to log to a file in your Rust program. Specifically, we will look at some of the options using YAML to configure the logging. What is log4rs From the crate description: “log4rs is a highly configurable logging framework modeled after Java’s Logback and log4j libraries.” For the log4rs crate’s page click here. Why log4rs What is good about log4rs? It offers an easy way to log to a file and it is highly configurable using a YAML config file, as well as through code. However,…
Rust Web3 connect to Ethereum blockchain: how to
In this article for semi-beginners, we are going to learn how to connect to Ethereum with the web3 crate and Rust. We will connect using a WebSocket and then retrieve the balance of our account. Finally, we will use a token smart contract to retrieve information about the token. Please note that we will be using the Rinkeby test network for our interactions. So, if an address for a smart contract or token doesn’t seem to work, make sure that you are using the Rinkeby network. Please look at my GitHub for the full project: rust-web3-basics-tutorial. Please also see this…
Crypto triangle arbitrage dashboard: how to, part 1
This article is part 1 of a series that will explain how to build a crypto triangle arbitrage dashboard using Rust and React. In this part 1, we will build the backend for the triangle arbitrage dashboard. The backend will gather data about trades for 3 coin pairs from the Binance WebSocket API. Then, it will calculate potential profits if we were to trade the pairs in sequence. Triangle arbitrage attempts to take advantage of price discrepancies between 3 assets that form a triangle on the same exchange. An example trade would be: BTC -> ETH -> BNB -> BTC.…
Warp data update loop: easy how to
What does “Rust Warp data update loop” mean? This article will describe how to create an infinite loop that sends data to clients connected to your WebSocket server in a thread separate from the main thread. This is useful when you want to build a system that periodically retrieves data from one or more sources and then needs to actively push that data to your client application. For example, a frontend dashboard that displays the data. The completed code project can be found on my GitHub, click here. This article will use the project from the following article: Rust Warp…
Rust Warp WebSocket server: learn how to now
In this article we will build a WebSocket server with Rust, using the warp framework. We will slowly go through the code building a simple version at first, and then add a bit more functionality to it. At the end of this article, we will be able to receive messages from the client and send something back in response. We will use this project as a base for future articles to build upon. We add a continuous data update loop to this project in the follow-up article Warp data update loop: easy how to. The repository with the complete Rust…
Easily connect to Binance WebSocket streams with Rust
In this article, we will look at how to connect to Binance WebSocket streams with Rust. We will be using the tungstenite library to make a WebSocket connection. For this tutorial, we will only use the public market data channels, so there is no need to register for an API key. Go to my Github to find the complete project here. This article is one of the first steps in a series of articles for building a triangle arbitrage dashboard using Binance cryptocurrency trading streams. Other articles in this series: The next step can be found at: Rust Warp WebSocket…
