Detailed Description

template<>
struct pqxx::string_traits< binarystring >

String conversion traits for binarystring.

Defines the conversions between a binarystring and its PostgreSQL textual format, for communication with the database.

These conversions rely on the "hex" format which was introduced in PostgreSQL 9.0. Both your libpq and the server must be recent enough to speak this format.

Member Function Documentation

◆ from_string()

static binarystring pqxx::string_traits< binarystring >::from_string ( std::string_view  text)
static

Start a block of deprecated code which may call other deprecated code.

Most compilers will emit warnings when deprecated code is invoked from non-deprecated code. But some compilers (notably gcc) will always emit the warning even when the calling code is also deprecated.

This header starts a block where those warnings are suppressed. It can be included inside a code block.

Always match the #include with a closing #include of "ignore-deprecated-post.hxx". To avoid mistakes, keep the enclosed area as small as possible.

End a code block started by "ignore-deprecated-pre.hxx".
