One of the more confusing examples for me to learn when studying Dave Macleod’s excellent “Rust in a Month of Lunches” was page 145. Check the “Rust Book” for the official description of the from trait : https://doc.rust-lang.org/std/convert/trait.From.html I modified the example to use cities in England to help me relate to it! Two cities, […]
If you are new to SurrealDB and Rust you may be interested in how to get the data from a Response or even be trying to parse a ‘Value’. The Response struct The secret is to make a struct that will contain the keys (field names) that are present in the response. You don’t want […]
Code plus screenshots – how to manipulate the layout in Rust + iced.rs Credit : https://jl710.github.io/iced-guide/index.html © Héctor Ramón (hecrj) for the iced logo. just using “row” Change “row” to “column” just using “column” Column is centered…but not the text! 🤔 Column is centered and the text! 😀 Centre the window – iced.rs – 0.13 […]
Let’s pick the code apart for a timelock smart contract and with a bit of help from chatGPT and the Stellar documentation we’ll make sure we understand every part of it. https://github.com/stellar/soroban-examples/blob/main/timelock/src/lib.rs Timelock This is how it works with Alice and Bob: In summary, the contract protects the funds by ensuring that only the designated […]
Testing Rust code for “signup” and checking the token. Add Scope and then you can create the JWT. Watch the YouTube video here: https://youtu.be/e4a8lOT_Gxg https://surrealdb.com Use the bearer token created by the rust code, not the one here as it will have expired WEBDOCK Linux VPS Hosting
In this article I show some code to web scrape EBAY using Rust and a proxy provided by ScrapeOps The code below uses the ScrapeOps endpoint : “https://proxy.scrapeops.io/v1/” and the requests are forwarded on to your chosen url to scrape. How to get an API key? You can get a free one, with 1000 tokens […]
We’ll convert png to jpg, but the same concept will apply to doing the reverse of this. You can grab png datasets from Kaggle If you just want to skip to the code, check out these links: What is a JPEG ? Let’s first understand the structure of a *.jpg file The structure of a […]
Using serde_json to Handle Fake Data in Rust When working with JSON data in Rust, serde_json provides a convenient way to parse and manipulate JSON values. In this post, we’ll demonstrate how to use serde_json::Value to create some mock data, simulate a search result, and extract specific fields from it. Creating Fake Data and Extracting […]
This article delves into a Rust program that showcases custom error handling, parsing, and validation. By leveraging the thiserror crate, we create descriptive error types to manage various parsing scenarios robustly. We’ll explore how the program defines an Animal struct, parses and validates integer strings, and utilizes generics and traits for flexible error reporting. Whether […]
