It encodes an interface with a set of recursive functions. If an error occurs when traversing the value, panic is called to unwind the stack to the top-level function call, which recovers from the panic and returns an appropriate error value (see the 'error' and 'marshal' methods of the encodeState type in [[https://golang.org/src/pkg/encoding/json/encode.go][encode.go]]). The convention in the Go libraries is that even when a package uses panic internally, its external API still presents explicit error return values. |
