It also won't merge structs inside maps (because they are not addressable using Go reflection). 10 11Usage 12 13From my own work-in-progress project: 14 15 type networkConfig struct { 16 Protocol string 17 Address string 18 ServerType string `json: "server_type"` 19 Port uint16 20 } 21 22 type FssnConfig struct { 23 Network networkConfig 24 } 25 26 var fssnDefault = FssnConfig { 27 networkConfig { 28 "tcp", 29 "127.0.0.1", 30 "http", 31 31560, 32 }, 33 } 34 35 // Inside a function [...] 36 37 if err := mergo.Merge(&config, fssnDefault); err != nil { 38 log.Fatal(err) 39 } 40 41 // More code [...] 42 43*/ 44package mergo 45
