// convert data to and from byte-level and textual representations.

|
// encoding/json, and encoding/xml. As a result, implementing an
|
|
// interface once can make a type useful in multiple encodings.
|
|
// Standard types that implement these interfaces include time.Time and net.IP.
|
|
// The interfaces come in pairs that produce and consume encoded data.
