## Declaration

func traverse<V>(visitor: inout V) throws where V : Visitor

#### Summary

Traverses the fields of the message, calling the appropriate methods
of the passed Visitor object.
This is used internally by:
* Protobuf binary serialization
* JSON serialization (with some twists to account for specialty JSON)
* Protobuf Text serialization
* Hashable computation
Conceptually, serializers create visitor objects that are
then passed recursively to every message and field via generated
traverse methods.  The details get a little involved due to
the need to allow particular messages to override particular
behaviors for specific encodings, but the general idea is quite simple.

### Parameters

| Name | Type | Summary |
| --- | --- | --- |
| visitor | V | - |
