Re: [go-nuts] Using reflect to call functions on struct members

I think this 40 second snippet of a talk by Rob Pike is apropos. It is not specific to your case, but speaks of reflection in general. On Thursday, January 18, 2018 at 5:20:26 PM UTC-5, Boone Severson wrote: > > Ok, asked a

Re: [go-nuts] Using reflect to call functions on struct members

Ok, asked and answered. Figuring out .Addr() was a key, as was finding the magic incantation to get a handle to a method. I'm curious if there's a better method. https://play.golang.org/p/49Yj9G0egRI package main import ( "fmt" "reflect" ) type FooTypeA uint8 type FooTypeB uint8 type MyStruc

Re: [go-nuts] Using reflect to call functions on struct members

(for completeness and future reference, I found how Addr() will let me use a pointer receiver https://play.golang.org/p/JSKduIPDV2e . However, I'm still at the place I was in the Go Playground link mentioned immediately above) On Thu, Jan 18, 2018 at 11:14 AM, Boone Severson wrote: > Thank you

Re: [go-nuts] Using reflect to call functions on struct members

Thank you for the response. I've chosen to have Validate() receive a copy of the value, but I still can't find Validate() in the list of Methods: https://play.golang.org/p/uCeCB-wv4Ku (run to see output) Any further advice? Thanks in advance. On Thursday, January 18, 2018 at 10:40:34 AM UTC-8,

[go-nuts] Using reflect to call functions on struct members

Hi, I've got structs containing custom types. I'm hoping to use reflect to create some fairly generic code to Validate() every field of a struct based on its type, but I can't seem to get the code right. Is this possible? I've set up a playground to show where I've gotten. https://play.golang
