◆ from_string() [1/2]
◆ from_string() [2/2]
Parse a string representation of a TYPE value.
Throws conversion_error if value does not meet the expected format for a value of this type.
- Warning
- A null value has no string representation. Do not parse a null.

inlinestaticnodiscardnoexcept |
Estimate how much buffer space is needed to represent value.
The estimate may be a little pessimistic, if it saves time.
The estimate includes the terminating zero.
◆ to_buf() [1/2]

◆ to_buf() [2/2]
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.
- Exceptions
-
| 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. |

Is conversion from string_view to TYPE supported?
When defining your own conversions, specialise this as true to indicate that your string traits support from_string.

◆ converts_to_string [2/2]
Is conversion from TYPE to strings supported?
When defining your own conversions, specialise this as true to indicate that your string traits support the conversions to strings.
