+// Package bson is an implementation of the BSON specification for Go:

+// The public API.
+
+// A value implementing the bson.Getter interface will have its GetBSON
+// method called when the given value has to be marshalled, and the result
+// of this method will be marshaled in place of the actual object.
+//
+// If GetBSON returns return a non-nil error, the marshalling procedure
+// will stop and error out with the provided value.
+type Getter interface {
+ GetBSON() (interface{}, error)
+}
+
+// A value implementing the bson.Setter interface will receive the BSON
+// value via the SetBSON method during unmarshaling, and the object
+// itself will not be changed as usual.
+//
+// If setting the value works, the method should return nil or alternatively
+// bson.SetZero to set the respective field to its zero value (nil for
+// pointer types). If SetBSON returns a value of type bson.TypeError, the
+// BSON value will be omitted from a map or slice being decoded and the
+// unmarshalling will continue. If it returns any other non-nil error, the
+// unmarshalling procedure will stop and error out with the provided value.
+//
+// This interface is generally useful in pointer receivers, since the method
+// will want to change the receiver. A type field that implements the Setter
+// interface doesn't have to be a pointer, though.
+//
+// Unlike the usual behavior, unmarshalling onto a value that implements a
+// Setter interface will NOT reset the value to its zero state. This allows
+// the value to decide by itself how to be unmarshalled.
+//
+// For example:
+//
+// type MyString string
+//
+// func (s *MyString) SetBSON(raw bson.Raw) error {
+// return raw.Unmarshal(s)
+// }
+//
+type Setter interface {
+ SetBSON(raw Raw) error
+}

+// SetZero may be returned from a SetBSON method to have the value set to
+// its respective zero value. When used in pointer values, this will set the
+// field to nil rather than to the pre-allocated value.

+// M is a convenient alias for a map[string]interface{} map, useful for
+// dealing with BSON in a native way. For instance:

+// for an equivalent map type. Elements in the map will be dumped in an
+// undefined ordered. See also the bson.D type for an ordered alternative.

+
+// D represents a BSON document containing ordered elements. For example:
+//
+// bson.D{{"a", 1}, {"b", true}}
