Learn import Rust fundamentals that you need in order to get started with writing Soroban smart-contracts for Stellar Blockchain

What is Rust?

• Statically typed language
• Systems programming language (lies betweeen LLP and HLP)
• No Garbage Collection -> Memory Management is Deterministic -> Predictible performance optimization and output

Rust documentation resources:

• The Rust book: https://doc.rust-lang.org/book/
• Rust by example: https://doc.rust-lang.org/rust-by-example/hello/print.html
• Rustlings: https://github.com/rust-lang/rustlings

Install Rust using command:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Run Rust program using command:

<!-- To compile rust program -->
rustc filename.rs

<!-- To execute the executable file -->
./filename.exe

  • Floating-Point Numbers
  • Booleans
  • Characters

• Compound Types: Store Multiple Values
