Row

A row returned when stepping over an SQLite prepared statement.

The data of each column can be retrieved:

using Row as a random-access range of ColumnData.
using the more direct peek functions.

Warning: The data of the row is invalid when the next row is accessed (after a call to ResultRange.popFront()).

struct Row {

import std.traits : isBoolean, isIntegral, isSomeChar, isFloatingPoint, isSomeString, isArray;;

import std.traits : isInstanceOf, TemplateArgsOf;;
