Introducing Rust
Many blockchains have selected Rust as their go-to programming to write their core protocol on which the rest of the architecture is built. There are plenty of reasons for this and since our book is about Rust for blockchain development, we need to understand why Rust is so popular for the blockchain use case.
In the following subsections, our focus will be on understanding the reasons why Rust is a perfect fit for blockchains.
The benefit of being statically typed
Rust adheres to static typing principles, requiring an explicit declaration of variable types, which are resolved during the compilation process. This allows the compiler to check if a variable can do what it’s supposed to, protecting against errors when the program runs.
In statically typed languages, the result or end product usually takes the form of a lower-level representation. Pre-compilation, the compiler possesses assurances for correctness and consistency regarding the structure...
