str_replace_all with multiple replacements

[Close-your-eyes]

The result of stringr::str_replace_all("abcd", pattern = c("a" = "d", "d" = "x")) is "xbcx". That means, patterns are replaced one after the other: 'a' first becomes 'd' and in second round 'd' becomes 'x'. So, 'a' becomes 'x'.

What do I have to do to get "dbcx" as result?

I expect it is not possible with stringr::str_replace_all. But, is there another function to do it and if not, is the behaviour I desire too weird to be covered by stringr::str_replace_all?

I don't know of any easy way to do that, sorry.
