## Detailed Description

### template<typename CHAR = char, typename TRAITS = PGSTD::char_traits<CHAR>>
class pqxx::basic_fieldstream< CHAR, TRAITS >

Input stream that gets its data from a result field.

Use this class exactly as you would any other istream to read data from a field. All formatting and streaming operations of `std::istream` are supported. What you'll typically want to use, however, is the fieldstream typedef (which defines a basic_fieldstream for `char`). This is similar to how e.g. `std::ifstream` relates to `std::basic_ifstream`.

This class has only been tested for the char type (and its default traits).
