'What's label currying in Prometheus?

In Prometheus, there's label currying. Some example methods are like CurryWith().

What's the meaning of it? Sorry I didn't find any documentation for this.

Problem might be related to that English is not my native language, and I don't understand curry from the function name.

Thanks!

In mathematics and computer science, currying is the technique of converting a function that takes multiple arguments into a sequence of functions that each takes a single argument.

It allows you to fill in some but not all label value. You can check it here: https://github.com/prometheus/client_golang/blob/master/prometheus/gauge.go#L246
