...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Prepares a statement server-side.
template< class CompletionToken> auto async_prepare_statement( string_view stmt, diagnostics& diag, CompletionToken&& token);
stmt
should be encoded
using the connection's character set.
The returned statement has valid() == true
.
If CompletionToken
is
a deferred completion token (e.g. use_awaitable
),
the string pointed to by stmt
must be kept alive by the caller until the operation is initiated.
The handler signature for this operation is void(boost::mysql::error_code, boost::mysql::statement)
.
