'run rustup's curl-fetched installer script non-interactively

I am trying to automate stuff which includes installing rust through

curl https://sh.rustup.rs -sSf | sh

This is interactive and queries for user-input to choose from i.e. "1" "2" or "3".

Not able to figure out, how to input.

Normally for apt-get, "-y" option try to capture and input for prompt.

Not sure, how it is done for curl.

How can I do this?

linux ubuntu
