Enable Edition 2024 in Rust

The error occurs because your Rust project is trying to use the edition2024 feature, which is not stabilized in your current Cargo version (1.75.0). To resolve this, you need to opt into the unstable edition2024 feature explicitly.

Steps to Fix:

Enable the edition2024 Feature: Open your Cargo.toml file and add the following line at the very top, before the [package] section:
```
cargo-features = ["edition2024"]
```
For example, your Cargo.toml might look like this:
```
cargo-features = ["edition2024"]

[package]
name = "your_project_name"
version = "0.1.0"
edition = "2024"
```
Use a Nightly Rust Toolchain: Since edition2024 is an unstable feature, you need to use the nightly Rust toolchain, as stable versions (like 1.75.0) don’t support it. Run the following commands:
```
rustup update nightly
rustup override set nightly
```
The first command updates the nightly toolchain, and the second sets your project directory to use the nightly toolchain.
Re-run the Build: After making these changes, try building your project again:
```
cargo build
```

Additional Notes:

The edition2024 feature is experimental and may change. Check the Rust documentation for updates on its status: Rust Edition 2024.
If you don’t need edition2024, you can revert to a stable edition (e.g., edition = "2021") in Cargo.toml to avoid using the nightly toolchain.
Ensure your rustup is up-to-date by running rustup update.

If you encounter further issues, share the contents of your Cargo.toml or any new error messages for more specific guidance.
