Memoization in Go

I'm curious what people are doing for memoization in #golang. I've looked around and haven't found great libraries for this which makes me wonder if I'm pursuing the wrong solution to a problem.

Caching the return values of functions based on the params has been useful to reduce load on downstream services, make things a bit faster on average and even add some level of consistency in functions that can be highly variable (which is an odd use case but nonethelass useful). But maybe there's a different pattern/idiom that's used in the Go ecosystem?
