From a3fbba1b2665e488a97ab5678ea1b8cd33aba39a Mon Sep 17 00:00:00 2001 From: Anmol Sethi Date: Mon, 16 Dec 2019 11:07:30 -0600 Subject: [PATCH 1/2] Remove Value interface and ForceJSON Realized we can replace ForceJSON now that we only marshal structs as JSON if they have a json struct tag and json.Marshaller can be used in place of Value as well so its not necessary. --- example_forcejson_test.go
