func Dump ¶

func Dump(v any) any

Dump converts an arbitrary value to a scalar value.

The purpose of this function is to provide an alternative to fmt verbs such as %#v or %+v that returns a value in a more human-readable format.

• Simple types, like numbers and strings and booleans, are returned as-is.
• For types that implement fmt.Stringer, the result of String is returned.
• For types that implement encoding.TextMarshaler, the result of MarshalText is returned.
• For types that implement json.Marshaler, the result of MarshalJSON is returned. If the result is a JSON string, number, or boolean, it is converted to a Go type.
• Byte slices and arrays are represented as hex strings.
• For types that implement error, the result of Error is returned.
• In maps, slices, and arrays, each element is recursively converted according to these rules and then represented as a JSON.

If a returned value is a JSON, it is returned as a json.RawMessage.
