Why Rust & What Is Rust
Why Rust & What Is Rust
Why Rust?
In system programming languages we basically face two complex problems which are difficult to crack i.e. Secure and Multithreaded code. For this Rust has added its own goals of memory safety and data-race-free concurrency.
What Is Rust?
Rust is a System programing language sponsored by Mozilla which describes it as a “safe, concurrent and practical language,” supporting functional…

You must be wondering what is so special about numeric data types in RUST, that we are focusing on them so much, definitely, you will get to know after finishing this blog.
Generally, other programming languages follow short, int, float, long, double etc as numeric data types as per their storage size and capacity while in RUST numeric data type are like :
i[size_in_bits] or u[size_in_bits]

Working with Rust: Formatting, Linting & Auto-completion
Working with Rust: Formatting, Linting & Auto-completion
Every language has its own toolset for writing effective and clean code, Rust is no different. So in this blog, we would be describing how to format the rust code, while working with different editors or IDE.
Formatting code is a mechanical task which takes both time and mental effort. By using an automatic formatting tool, a programmer is relieved of this task and can concentrate on more…

Lagom 1.4: Response compression | GZip Encoding
Lagom 1.4: Response compression | GZip Encoding
In the previous blog, we discussed response compression using GZip filter for Lagom 1.3. Here, we will go over the steps we use to add similar response compression in Lagom 1.4. The steps remain the same with minor changes due to underlying changes that came as Lagom upgraded from Play 2.5 to Play 2.6.
Step 1: The code
The first step is to write the code for our compression filter. We design a…

ScalaFP: Let’s Find The Reasons Behind Monads.
Monads in Functional Programmingplay an important role but they mostly confuse the beginners. One of the reasons for the confusion is that they mostly have a knowledge of imperative style programming, where they have no idea about function composition and its importance. In the terms of functional programming, the composition is the root where we have a set(Z) and we compose the elements of the…

Migrating to Lagom 1.4.x in Java
This blog will help you to migrate your Lagom service from 1.3.x to 1.4.x. Here, I have shared few of the things that need to be considered while migrating your Lagom version.

Custom ErrorHandlers and Lagom
Custom ErrorHandlers and Lagom
Hello everyone,
it’s been quite a while now since I started working on Lagom(java) and it was only recently when I came across a scenario wherein I was required to override the ErrorHandler provided by Play in my Lagom microservice. As you all already know that Lagom is built on top of Play and Akka, so there will be times when we’ll be required to override the behavior and functionality provided…

Best Practices for Cassandra Data Modeling
People new to NoSQL databases tend to relate NoSql as a relational database. But there is quite a difference between those. For people from relation background, CQL looks similar but the way to model it is different. Picking the right data model is the hardest part of using Cassandra. I will explain to you the key points that need to be kept in mind when designing a schema in Cassandra. By…

Cassandra User-defined types(UDTs)
Cassandra supports a rich set of data types that we can use to create our tables. You can refer to all the supported data types from here. Other than that Cassandra also provides support to user-defined data types.
User-defined types (UDTs)can attach multiple data fields, each named and typed, to a single column. The fields used to create a UDT may be any valid data type, including collections…
