# Backend internal interview (rust) - improved
|
|
|
|
This **Improved** branch is a rather disruptive approach to the [initial proposal](https://repo.jesusperez.pro/jesus/be-technical-interview-rust)<br>
|
|
[Branch basic-fixed](https://repo.jesusperez.pro/jesus/be-technical-interview-rust/src/branch/basic-fixed) tried to solve proposal from initial code
|
|
as a **continuity effort** with the necessary changes and some improvement adjustments such as the **parallel input processing**
|
|
|
|
> [!NOTE]
|
|
> A full refactoring done for <u>better quality, maintenance and readability</u>. (Structs, implementaitions, settings for multiple inputs, etc). <br>
|
|
> It is able to **process multiple metrics in parallel**. <br>
|
|
|
|
## In summary
|
|
|
|
- [x] Define a basic model, easily to extend and modify. **Abstraction / Generic**.
|
|
- [x] Structs and implementations to specific metricis traitments. **Modular appoach**.
|
|
- [x] Settings and configuration for interactive and non interactive processing (batch mode) **Customize on context**.
|
|
|
|
See [main changes](/jesus/be-technical-interview-rust/src/branch/improved/CHANGES.md)
|
|
|
|
> [!IMPORTANT]
|
|
> Use [ABOUT](ABOUT.md) content for quick [Verification](ABOUT.md) (it requires download and build)
|
|
|
|
## Benefits
|
|
|
|
Elements items come from [main changes](/jesus/be-technical-interview-rust/src/branch/improved/CHANGES.md)
|
|
|
|
| Element | Benefit |
|
|
|----------------- |---------|
|
|
| Generic traits | Group generic task for metric processing, steps / tasks separation |
|
|
| Structs | Customize atributes and implementation for specific target or patterns |
|
|
| Enums with values| Associate attributes metrics and values, easy to add new attributes or combine with different values at once |
|
|
| Vectors | Simplify types / grouped in structs, priorize vectors type, easy to iterate, filter, sort, etc |
|
|
| Const and Config | Group main const, define metric targes and operations in declarative mode for non intective traitment |
|
|
| Command line args| Help to run in terminal as a cli |
|
|
| Unit Tests | Verify some operations results |
|
|
|
|
> [!TIP]
|
|
> After download repository and build:
|
|
|
|
> - Use [howto](howto.md) for command, options, etc.
|
|
> - Build documentation and browse content whit source code (instruction in [about](ABOUT.md))
|
|
> - Files layout notes in [layout.md](layout.md)
|
|
|
|
|
|
## Ideas not included
|
|
|
|
- **Async I/O** to scale and performance ?
|
|
- Other Thread alternatives like [Tokio](https://tokio.rs/) or/and [Coroutines](https://doc.rust-lang.org/std/ops/trait.Coroutine.html)
|
|
- Benchmarking for optimization
|
|
- More **tests**
|
|
- Run as **API mode** not only as batch processing
|
|
|
|
> [!NOTE]
|
|
> Code is in a private repository with several other branches.<br>

|
|
There are several branches developed as proposal:
|
|
|
|
- [Basic fixed one](/jesus/be-technical-interview-rust/src/branch/basic-fixed)
|
|
> A basic code review, fixed with minor and essential changes to work as expected. <br>
|
|
> Tests are included for verification. <br>
|
|
|
|
- [Improve one](/jesus/be-technical-interview-rust/src/branch/improved)
