Detailed Description

template<typename T, typename E>
struct donner::editor::Result< T, E >

A success-or-error value used by the viewport SVG exporter.

Either holds an exported value of type T, or a human-readable error string of type E. Donner's ParseResult is purpose-built for parser ParseErrors; the exporter wants a plain string error message, so this lightweight result type is used instead.
