The MappedRows iterator for
rusqlite returns a
rusqlite::Result on each iteration, but I would like to map that to a custom error so as not to expose rusqlite in the public api.
The problem is that I don't know how to wrap that iterator and then return it from a function. The iterator in question references a Statement , which in turn references a
Connection . I thought I could store the
Statement along with the
MappedRows in a struct and return that, but I'm having no luck.
Does anyone know of the correct approach for this?
