From the guide, rustup will check for updates to itself (in addition to the toolchain updates) every time you run rustup update. You could also exclusively update rustup by running rustup self update.

r/rust on Reddit: PSA: new rustup version might break your CI soon. Prepare!
March 5, 2025 -
Rustup 1.28.0 was released today (https://blog.rust-lang.org/2025/03/02/Rustup-1.28.0.html). It includes a breaking change where the Rust toolchain from rust-toolchain.toml files won't be installed by default anymore.
If you run your CI on GitHub Actions, and use rust-toolchain.toml, you might want to take a look at updating your CI workflows, for example with the workaround mentioned in the blog post (rustup show active-toolchain || rustup toolchain install). Otherwise your CI will break when GitHub actions runner image will update to rustup 1.28.0 (which might happen in the upcoming few weeks, I assume).
EDIT: The breaking change was reverted in Rustup 1.28.1 (https://blog.rust-lang.org/2025/03/04/Rustup-1.28.1.html).

July 21, 2024 - take example arch linux, normally super simple to configure, the arch linux page for rust contains (1) native install (2) rustup install, (3) rustup via arch linux package (4) rustup via upstream installation script (5) rustup toolchain install via "usuage". a normal operating system update does NOT update rust, it needs separate love.
