Is there a way to use the new go embed feature with echo?

Question

Is there a way to use the new go embed feature with echo? I would like to serve files with the echo static middleware from files embedded with go embed. https://tip.golang.org/pkg/embed/ https://echo.labstack.com/guide/static-files

This issue links to a gist from Mark Wolfe that demonstrates a pretty straight forward approach. The core of the approach is:

// content holds our static web server content.
//go:embed static/*
var content embed.FS

var contentHandler = echo.WrapHandler(http.FileServer(http.FS(content)))
// The embedded files will all be in the '/static' folder so need to rewrite the request (could also do this with fs.Sub)
var contentRewrite = middleware.Rewrite(map[string]string{"/*": "/static/$1"})

func SetupRoutes(...) {
   e.GET("/*", contentHandler, contentRewrite)
}
