Detailed Description

template<class T>
struct mysql::serialization::Archive_binary_field_max_size_calculator< T, 0 >

helper structure created for partial specialization of get_max_size function of Archive_binary, specialization for defined size equal to 0.

0 means default maximum size: for std::string default maximum size is unlimited, for variable length integer - sizeof(Type)+1, for double Type it equals to sizeof(Type) For unlimited strings, get_max_size is disabled (code won't compile)

Template Parameters

T	type of field

inlinestaticconstexpr

Calculates maximum encoded size of the variable-length integer fields.

Returns
