`Rust Constructor` is an open-source project, but it has no direct relationship with the `egui` development team!

## Version Update Information
- The current latest version is `v2.7.1`. The main updates include:
- Added `RequestMethod` to manage methods for requesting to skip rendering queue;
- Replaced `[String; 2]` with `RustConstructorId` in certain fields;
- Updated `request_jump_render_list` to now locate rendering resources and bypass queue through resource reference inspection;
- Added `unsafe_request_jump_render_list` method to preemptively jump rendering queue regardless of referenced resource existence;
- Added `get_box_resource` and `get_box_resource_mut` methods to retrieve resources without specifying concrete types.

## Introduction
- `Rust Constructor` is a Rust graphical development library built on egui, including commonly used functions such as timers, resource storage, and error handling.
- `Rust Constructor` released its first version in `2025.2`, and today's `Rust Constructor` has undergone earth-shaking changes compared to that time.
---
## Quick Start
- To introduce `Rust Constructor`, please add `rust_constructor = "x.y.z"` (please replace xyz according to your needs) to `toml`.
- If you want to start `App` and perform some simple operations, it is recommended to refer to the [official documentation of egui](https://github.com/emilk/egui).
- You can refer to the official tutorial of `Rust Constructor` [Rust Constructor Guide](https://github.com/ChepleBob30/Rust-Constructor-Guide).
---
## Purpose of Creating Rust Constructor
We encountered some problems that `egui` could not solve during the development of [Targeted Vector](https://github.com/ChepleBob30/Targeted-Vector), so we expanded many tools. In order to allow more people to develop conveniently, we created `Rust Constructor`.

## FAQ
- Q1: Which platforms does `Rust Constructor` support?
- A1: `macOS` and `Windows` have been confirmed to be fully supported, and other platforms depend on `egui` support.
- Q2: What is the difference between `Rust Constructor V2` and `V1`?
- A2: The original architecture was modified to conform to the structure of the library `crate`, published on [crates.io](https://crates.io/), and added an official guide.
- Q3: Why do I get an error when calling a resource?
- A3: Please ensure that you have added the resource through the `add` method and there are no spelling errors.
- Q4: How to modify resources?
- A4: Take out the resource through `get_resource_mut`.
- Q5: What should I do if I encounter unknown error prompts?
- A5: Prioritize checking the `RustConstructorError` definition in the `Rust Constructor` source code, find the problem you triggered and correct it.
- Q6: Why is there only `V2` of `Rust Constructor` on `crates.io`?
- A6: `Rust Constructor V0` and `Rust Constructor V1` are essentially bloated projects with many redundant functions and meaningless code, so they were not released.
