func CopyExportedFields ¶

func CopyExportedFields(dst, src any)

CopyExportedFields copies all exported fields from src to dst, regardless of their current values. Useful for copying full configurations or cloning objects.

Note: Unexported fields (lowercase) will be ignored.

func MergeZeroFields ¶

func MergeZeroFields(dst, src any)

MergeZeroFields copies non-zero fields from src to dst, but only for fields in dst that are currently zero. dst and src must be pointers to structs of the same type.

Example:

MergeZeroFields(&userConfig, &defaultConfig)

Only fields in userConfig that are zero-valued will be replaced by corresponding values from defaultConfig.

func StructToMap ¶

func StructToMap(input any) map[string]any

StructToMap converts an exported struct (or a pointer to one) into a map[string]any. Only exported fields will be included in the map.

Useful for logging, serializing, or dynamic field access.

Example:

m := StructToMap(user)
fmt.Println(m["Name"], m["Active"])

func ZeroStruct ¶

func ZeroStruct(v any)

ZeroStruct resets all settable fields in a struct to their zero value. Takes a pointer to a struct.

Example:

ZeroStruct(&config) // config.Name = "", config.Count = 0, config.Enabled = false, etc.
