Understanding the Differences
The article aims to enlighten developers about the differences in using Rust as a programming language when working with Solana. However, it does not address the basics of Blockchain or Solana. It also omits core Solana concepts such as Programs, Accounts, Fees, and Transactions. These essentials must be understood to program effectively in Solana.
Project Setup
Despite the transition, on-chain programs for Solana in Rust remain Rust programs. They follow the standard Rust project with a /src folder and Cargo.toml file in the root. However, there are a few crucial differences.
Project Dependencies
Program Entrypoint
Instead of a main function, Solana programs use the entrypoint! macro. This symbol, exported and subsequently called by the Solana runtime when the program runs, calls a given function, which must have a specific type signature.
In conclusion, while Rust and Solana share many similarities, there are key differences that developers need to understand to transition smoothly and effectively. By understanding these differences and leveraging the resources provided, developers can embark on their Solana journey confidently.
