You cannot statically prevent someone from willfully assigning
to a variable of accessible type (eg. a function call parameter).
If you're just after sanity check there are many ways.

At runtime you can eg. use a map: https://play.golang.org/p/5rwJLFpU3a4

For compile time - you can use stringer tool to generate numerical constants 
mapped to strings.

hope this helps,
