• Rust | A bunch of links to blog posts, articles, videos, etc for learning Rust

Learn by Practice

• Exercise | Rust | Polkadot Blockchain Academy - Qualification Exam: This exam is maintained by the Polkadot Blockchain Academy, for the benefit of the entire Rust community. The Academy accepts individuals modestly skilled in Rust, and maintains this exam to help everyone asses their proficiency being of a level we would consider for the program.
• Exercise | Rust | Rust by Practice: Practice Rust with challenging examples, exercises and projects

Courses, Videos & Tutorials

• Couuse | Rust | Design Patterns in Rust: Learn common design patterns & anti-pattern in Rust
