How to Install rust on alpine?

Rust is a multi-paradigm, general-purpose programming language designed for safety and performance, especially safe concurrency. It is notable for enforcing memory safety. It is syntactically similar to C++ and is considered a systems programming language with the mechanisms for low-level memory management, but it also offers high-level features such as functional programming. Alpine Linux is an independent, non-commercial, general-purpose Linux distribution designed for power users who appreciate security, simplicity, and resource efficiency.

Features of Rust

• Performance: Rust aims to be as efficient and portable as idiomatic C++ without sacrificing safety.
• Memory Safety: It is designed to be memory safe.
• Memory Management: It doesn't use automated garbage collection and provides deterministic management of resources with very low overhead.
