question about implementing dynamic data sources

[sijad]

I'm trying to create dynamic data source to be able define resolvers similar to samsarahq/thunder:

type Friend struct {
  FirstName string
  LastName string
}

func (f *Friend) FullName() string {
  return fmt.Sprintf("%s %s", f.FirstName, f.LastName)
}

I need to pass parent value (f *Friend) to its resolvers, but I'm not sure how this can be implemented using TypeFieldConfiguration and datasources.

I really appreciate any hints or examples.

Hey, thanks for trying this library.
Does this help?

thanks,

Update: yes that was useful, thanks again

I'm looking for a way to pass an struct instance (e.g. f *Friend) to datasource resolver (e.g. func (f *Friend) FullName() string) or func FullName(f *Friend) string))
resolver should be able to access to the object instance somehow, one way might be to recreate TypeFieldConfiguration with each request and pass the instance via config, I'm note sure how efficient that'd be though or is there a better way?
