Function Project

expr/result_type.go:234–236

Project creates a ResultTypeExpr containing the fields defined in the view expression of m named after the view argument. The resulting result type defines a default view. The result type identifier is computed by adding a parameter called "view" to the original identifier. The value of the "view"

(rt *ResultTypeExpr, view string)

// individual attributes may use a different view. In this case Project uses
// that view and returns an error if it isn't defined on the attribute type.
func Project(rt *ResultTypeExpr, view string) (*ResultTypeExpr, error) {
	return project(rt, view, make(map[string]*AttributeExpr))
}

func project(rt *ResultTypeExpr, view string, seen map[string]*AttributeExpr) (*ResultTypeExpr, error) {
