SQLite

Компонент, который позволяет подключаться к SQLite.

Реализует интерфейс Connector который наследуется от интерфейса driver.Connector, который доступен в контейнере объектов если этот компонент используется напрямую.

Пакет предоставляет метод NewDataBase, который возвращает ссылку на объект sql.DB, который будет сконфигурирован на основе коннектора из этого пакета.

Объект конфигурации.

type Config struct {
	DSN string
}

Описание полей:

Поле	Описание	Значение по умолчанию
DSN	Строка подключения к SQLite, этот параметр может быть передан одним из 3-х методов: - флаг командной строки --db.sqlite.dsn - переменная окружения DB_SQLITE_DSN - значение в конфиг файле db.sqlite.dsn	<os_temp_dir>/db
