Advanced Types in Rust are quite helpful

Reading Time: 3 minutes In this blog, we will discuss the advanced types available in Rust. Creating Type Synonyms with Type Aliases Rust provides the ability to declare a type alias to give an existing type another name. For this, we use the type keyword. For example, we can create the alias Kilometers to i32 like so:  Values that have the type Kilometers will be treated the same as values of type i32: Because Kilometers and i32 are the same type, we can add Continue Reading

Updates in Rust 2021 edition

Reading Time: 2 minutes The new edition of Rust is here. The edition 2021 of Rust have many interesting changes in it. Let us have a look at some of the changes in edition 2021. Additions to the prelude The TryInto, TryFrom and FromIterator traits are now part of the prelude. This might make calls to trait methods ambiguous which could make some code fail to compile. However, adding a trait to the prelude can break Continue Reading

Solana – Wallet Creation and Sending Tokens

Reading Time: 4 minutes Solana is an open-source project implementing a new, high-performance, permissionless blockchain. It is also the most performant permissionless blockchain where a network of 200 physically distinct nodes supports a throughput of more than 50,000 transactions per second. Solana has innovated a mempool-less transaction forwarding protocol. A mempool is a set of transactions that have been submitted to the network and are yet to be processed by the Continue Reading

Error handling in Solidity is very useful

Reading Time: 3 minutes Hello guys, here is another blog on Solidity. Check out my previous blog on Value types in Solidity. In this blog, we will see how to do error handling in Solidity. Solidity uses state-reverting exceptions to handle errors. Such an exception undoes all changes made to the state in the current call and all its sub-calls and reports the error to the caller. When exceptions Continue Reading

Box Pointers in Rust make recursive types possible

Reading Time: 3 minutes Overview A pointer is a general programming concept for a variable that contains an address in memory. In Rust, we have smart pointers in addition to normal pointers. Smart pointers are data structures that not only act as a pointer but also have additional metadata and capabilities. Box pointers are one of the smart pointers in Rust. Box Pointers Boxes allow you to store data on the heap Continue Reading

Value Types In Solidity

Reading Time: 3 minutes Solidity is an object-oriented, high-level language for creating smart contracts. Smart contracts are programs that decide the behaviour of accounts within the Ethereum state. Solidity is a statically typed language. It supports inheritance, libraries and complex user-defined types among other features. With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. There are various data types in solidity Continue Reading

Carpooling Chain – Cab Booking made better

Reading Time: 3 minutes About Carpooling Chain is a decentralized blockchain solution built with the objective of eliminating the need for a central authority to book cabs. The blockchain backend for Carpooling chain is build using Substrate. Substrate is a next-generation framework for blockchain innovation. It comes with everything you need to build your blockchain.  Substrate is a completely free and open-source project. It is built using Rust and WebAssembly. Rust is designed for Continue Reading

Message Passing in Rust Threads is very helpful

Reading Time: 3 minutes Rust has been the most loved programming language for the last five years in a row. It is a low-level statically-typed multi-paradigm programming language that’s focused on safety and performance. Rust has facilities for message passing through an mpsc channel which allows various threads to communicate. Rust solves problems that C/C++ has been struggling with for a long time, such as memory errors and building concurrent programs. Due to the borrow checker, Rust can prevent data races at compile-time. Data races Continue Reading

Submit Extrinsic from Custom Pallets using Polkadot Js API

Reading Time: 3 minutes Substrate is a next-generation framework for blockchain innovation. It comes with everything you need to build your blockchain. Substrate is a completely free and open-source project. It is built using Rust and WebAssembly. Rust is designed for creating fast and inherently safe software. Substrate is like a template from which you can make your own application-specific blockchain to add custom functionalities specific to one use case or group of Continue Reading

Concurrency in Rust is indeed fearless

Reading Time: 3 minutes In modern operating systems, the executed program’s code is run in a process, and the operating system manages multiple processes at once. Within your program, you can also have independent parts that run simultaneously. The features that run these independent parts are called threads. A thread is a part of the process that runs along with the main process using a technique called context-switching. So, we can Continue Reading

Superpowers of Unsafe Rust

Reading Time: 4 minutes In the previous blog, I discussed one of the superpowers of Unsafe Rust which is dereferencing a raw pointer. In this blog, we will see another feature of unsafe rust. Rust has wonderful borrowing and ownership rules that take care of all the memory safety issues. It is one of the leading languages. More than 9 companies including Dropbox, Coursera, Figma, npm, Microsoft, Cloudflare, Facebook, Amazon and Discord use Continue Reading
