Hi Galen,
No, that is not currently supported, the current idiomatic way would be to
pass those values to the struct implementing the Statefun interface.
type MyFunc struct { someRuntimeInfo string } func (m *MyFunc) Invoke(ctx
statefun.Context, message statefun.Message) error { } func main() { builder
:= statefun.StatefulFunctionsBuilder()
f := MyFunc { someRuntimeInfo: "runtime-provided" } builder.WithSpec
(statefun.StatefulFunctionSpec{ FunctionType: statefun.TypeNameFrom(
"example/my-func"), Function: f })
http.Handle("/statefun", builder.AsHandler())
_ = http.ListenAndServe(":8000", nil) }
Would this work for you? Or what is the context (pun intended) you are
looking for?
