What is the equivalent of JSP's c:set in a Ruby on Rails view?

Question

I'm using Rails 5. What is the equivalent of JSP's c:set in a Rails view? In JSP you can set a page variable like so

<c:set var="myVar" value="myValue" />

How do I do that in a Rails view? Note that I'm invoking this logic from within a loop in my Rails view so each iteration could set the variable to something else. As such, I do not want any logic in my controller, only in my view.

A typical Rails app uses ERB. This can look like:

<%- myVar = myValue %>
