Their style is pervasive in Rust, such as in the standard library, so I would personally apply a when-in-rome philosophy. FWIW something like `.text("hello")` I would expect to see in a builder-pattern but not in a setter for an object that's already built.

That being said I don't particularly understand your conception of a method. They are both methods. The getter ought to have a shorter name since it is probably called more frequently and because it inherently has less of an impact -- this goes along with the principle that names that demand attention should be larger and easier to notice.

I think which to use in general Rust code depends on the purpose of your type.

A builder type like `Command` will have unqualified setters and `get_` qualified getters.

For record-like-structs, I think unqualified getters becomes preferred and `set_` qualified setters.

This style is aligned with protocol buffers, which is aligned with the style of protos in C++.
