Function unmarshal

http/codegen/service_data.go:2967–2969

unmarshal initializes a data structure defined by target type from a data structure defined by source type. The attributes in the source data structure are pointers and the attributes in the target data structure that have default values are non-pointers. Fields in target type are initialized with t

(source, target *expr.AttributeExpr, sourceVar string, sourceCtx, targetCtx *codegen.AttributeContext)

//
// sourceCtx, targetCtx are the source and target attribute contexts
func unmarshal(source, target *expr.AttributeExpr, sourceVar string, sourceCtx, targetCtx *codegen.AttributeContext) (string, []*codegen.TransformFunctionData, error) {
	return codegen.GoTransform(source, target, sourceVar, "v", sourceCtx, targetCtx, "unmarshal", true)
