示例1: loadDoc
// loadDoc converts from protobufs to a struct pointer or
// FieldLoadSaver/FieldMetadataLoadSaver. The src param provides the document's
// stored fields and facets, and any document metadata. An additional slice of
// fields, exprs, may optionally be provided to contain any derived expressions
// requested by the developer.
func loadDoc(dst interface{}, src *pb.Document, exprs []*pb.Field) (err error) {
fields, err := protoToFields(src.Field)
if err != nil {
return err
}
facets, err := protoToFacets(src.Facet)
if err != nil {
return err
}
if len(exprs) > 0 {
exprFields, err := protoToFields(exprs)
if err != nil {
return err
}
// Mark each field as derived.
for i := range exprFields {
exprFields[i].Derived = true
}
fields = append(fields, exprFields...)
}
meta := &DocumentMetadata{
Rank: int(src.GetOrderId()),
Facets: facets,
}
switch x := dst.(type) {
case FieldLoadSaver:
return x.Load(fields, meta)
default:
return loadStructWithMeta(dst, fields, meta)
}
}
