rustup: Use the nightly toolchain when inside the current project, but leave global settings unchanged.

rustup

$ rustup override set nightly

try on your machine

The command "rustup override set nightly" is used in Rust programming language development to set the active toolchain to nightly.

In Rust, the toolchain refers to the specific version of the Rust compiler and associated tools that are being used. Rustup is a command-line tool used to manage multiple Rust installations and switch between different toolchains.

By running "rustup override set nightly", you are instructing rustup to set the active toolchain to the latest nightly version. "Nightly" is the term used for unstable and frequently updated versions of Rust. It contains the latest features, improvements, and bug fixes that are being developed but may not be thoroughly tested or have backward compatibility guarantees.

Setting the active toolchain to nightly allows you to use the latest language features and experiment with cutting-edge functionality. However, keep in mind that code written or compiled with the nightly toolchain may not work on stable Rust versions or may require additional updates as the language evolves.
