Fix the 'edition 2024 is not yet stable' error by changing the edition field in Cargo.toml to 2021.
Change the edition field in your Cargo.toml file from 2024 to 2021 because the 2024 edition is not yet stable. Edit the [package] section to use the latest stable edition.
[package]
name = "your_project_name"
version = "0.1.0"
edition = "2021"
Run cargo build again to compile your project successfully.
Rust editions are like different versions of the language rules that your project follows. The 2024 edition is a future version that hasn't been officially released yet, so your computer doesn't know how to use it. Switching to the 2021 edition tells your project to use the current, stable set of rules that everyone is using right now.
