Re: [go-nuts] Safeness of using reflect.Type as a map key instead of reflect.Type.Name() ?
Yes, it's conventional to use reflect.Type as a map key. In fact, you should do that because not all types have different names, even if they're in the same package.

Bonjour Christophe, Yes, it is safe to use reflect.Type as a key. Even if that type was loaded from another shared library through 'plugin'. At least that's how it is supposed to work :) -s sent from my droid On Sat, Aug 18, 2018, 11:40 Christophe Meessen wrote: > I need to index data by type and I have two options: > - use a string as key and index the string returned by reflect.Type.Name() > - use reflect.Type as key > > I have the impression that indexing by reflect.Type would be slightly more > speed and space efficient, but I'm unsure if the relation between > reflect.Type and reflect.Type.Name() is bijective. > > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Safeness of using reflect.Type as a map key instead of reflect.Type.Name() ?
I need to index data by type and I have two options: - use a string as key and index the string returned by reflect.Type.Name() - use reflect.Type as key I have the impression that indexing by reflect.Type would be slightly more speed and space efficient, but I'm unsure if the relation between reflect.Type and reflect.Type.Name() is bijective. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
