This post shows how to modify a struct instance in a function. It uses the mutable shared borrowing to pass a mutable reference as an argument to a function. Struct And Instance Consider the following Person struct. It has two… Continue Reading
This post shows how to build a Ubuntu 18.04 Docker image with installed Rust. We can use the image to build Rust applications, but the codes are in the host Windows system. When we compile the codes, we need to… Continue Reading
Understanding what references are in Rust and how to use them is crucial. A reference is a pointer to a memory location. A location where the data we’re interested in reside. A reference is not the same as the traditional… Continue Reading
There are a few ways to define an enum variant and, as a result, to use it when creating match expressions. We can define a variant in three ways – one-word, Tuple-like, or Struct-like. Match One-Word Enum Variants Let’s say… Continue Reading
We can create custom data types in Rust using struct, trait, and enum. A struct is a composite data type that groups variables in a memory block. These variables are then accessible via the struct’s instance – also referred to… Continue Reading
Rust has two types of core data types – scalar and compound. Scalar types are single-value types, while compound types are multi-value types. Integer Data Types An integer data type is one of Rust’s core data types that represents a… Continue Reading
Variables in Rust are similar to variables in other high-level programming languages, and how we declare and use them are pretty straight-forward. There are several types of variables, and their declaration may differ from each other. Types Of Variables In… Continue Reading
R2D2 is a connection pool for Rust applications, e.g., Actix-Web, that use databases like MySQL. Opening and closing a database connection is an expensive operation. With connection pooling, the database connection creation happens once, and the application can reuse it… Continue Reading
Rust Generics is a language feature for code reuse in multiple contexts using different actual types for Structs, Functions, Methods, and Enums. Moreover, they allow for concise and clean codes by minimizing boilerplates while providing type-safety. When we use Generics,… Continue Reading
If you are new to Rust, choose Rust Stable over Nightly to make your life and other people’s lives simple – may apply to both crate producers and consumers. There are three types of Rust compiler – Nightly, Beta, and… Continue Reading
