Magisk is a suite of open source software for customizing Android, supporting devices higher than Android 6.0.

The native part is written in Rust.

A joke about rust infrastructure. It becomes obsolete as time goes.

1. avoid uneccessary default features
2. use specialized lighter crates

I have the same idea for a node js backend serving a fancy UI :)

It would be better to split the UI and the server while developing to benefit from hot reloading.

Example: https://git.sr.ht/~pyrossh/rust-embed/tree/master/item/examples/axum-spa/main.rs

• relying on shared mutation
• treat the compiler as something trying to help
• ignoring proper module organization

You have to unlearn a few habits.

1. Writing Rust code like other languages
2. Neglecting the most important 20% of Rust. Trying to learn everything at once: you don't need to learn all at once. Focus on the 20% that gives the 80%.
3. Being a productive procrastinator: watch a video or read a blog post.
4. Thinking you can vibe code Rust like JS...

Hands on practice! The programmer has to internalize the concepts of Rust. Getting a grasp is not enough.

Replace the standard DefaultHasher to ahash::{AHashMap, AHashSet} to gain 18% improvements.

I don't understand some things here

• gen blocks: similar to python generators as far as I understand. They are lightweight compared to the classic Iterator pattern
• default field values (and avoid new() for it)
• inner structs
• never type
• try expressions

The ability to run scripts is also a great feature imho.

Create a type similar to another existing type :O

Some interesting statistics.

Rust interact with other parts of the codebase through

1. Rest API (56%)
2. Language interop (44%)
3. RPC (21%)
4. WebAssembly /WASI (19%)

Projects developed in Rust are:

1. CLI tools (40%)
2. Systems programming (38%)
3. Web development (35%)
4. Desktop / GUI applications (21%)
5. Network programming (17%)
6. Embedded / IoT (12%)
7. Academic /Scientific / Numeric (9%)
   and more games, databases, DevOps, Security, data science / ML / AI, Blockchain, ...

As for why: write safer code, build high-performance applications, iterest or fun, improve skills and career opportunities (stay competitive in the industry), handle concurrency or multithreading safely, ...

How to learn?

• official rust documentation (95%)
• books (32%)
• video or podcasts (19%)
• online courses (12%)
• University or academic coursework (5%)
  and employer-provided training, rust training companies, ...

In the meantime, it consumes 10 times more resources than the tool htop
