struct pqxx::string_traits< range< TYPE > >
String conversions for a range type.
Conversion assumes that either your client encoding is UTF-8, or the values are pure ASCII.
Return a string_view representing value, plus terminating zero.
Produces a string_view containing the PostgreSQL string representation for value.
- Warning
- A null value has no string representation. Do not pass a null.
Uses the space from begin to end as a buffer, if needed. The returned string may lie somewhere in that buffer, or it may be a compile-time constant, or it may be null if value was a null value. Even if the string is stored in the buffer, its begin() may or may not be the same as begin.
The string_view is guaranteed to be valid as long as the buffer from begin to end remains accessible and unmodified.

| pqxx::conversion_overrun | if the provided buffer space may not be enough. For maximum performance, this is a conservative estimate. It may complain about a buffer which is actually large enough for your value, if an exact check gets too expensive. |
