Typedef Documentation

Error_ptr

using mysql::utils::Error_ptr = typedef std::unique_ptr<mysql::utils::Error>

Enumeration Type Documentation

Return_status

enum class mysql::utils::Return_status

strong

Simple, strongly-typed enumeration to indicate internal status: ok, error.

Enumerator
ok	operation succeeded
error	operation failed

Function Documentation

concat()

template<class... Args>

std::string mysql::utils::concat

(

Args...

args

)

Convert all the arguments to strings and concatenate the strings.

This feeds all arguments to a std::ostringstream, so supports all types for which operator<<(std::ostringstream&, ...) is defined.

Parameters

args	Arguments to concatenate.

Returns

The resulting std::string.

enum_max()

template<typename Enum_type >

constexpr Enum_type mysql::utils::enum_max ( )

inlineconstexpr

Template function that returns maximum valid constant that can appear in the enumeration type.

It must be specialized for each enumeration type serialized

Template Parameters

Enum_type

Type of the enumeration that will be returned

Returns

Last valid enumeration constant within Enum_type

enum_max< gtid::Gtid_format >()

template<>

constexpr gtid::Gtid_format mysql::utils::enum_max< gtid::Gtid_format > ( )

inlineconstexpr

Specialization of enum_max method for Gtid_format.

Returns

Maximum Gtid_format constant that can appear

to_enumeration()

template<typename Enum_type , typename Integral_type >

constexpr std::pair< Enum_type, Return_status > mysql::utils::to_enumeration ( Integral_type  value )

inlineconstexpr

Helper function that converts value of enumeration underlying type into enumeration type constant.

Template Parameters

Enum_type	Type of the enumeration that Integral_type parameter is converted into
Integral_type	Type of the enumeration parameter that gets converted into the Enum_type

to_underlying()

template<typename Enum_type >

constexpr decltype(auto) mysql::utils::to_underlying ( Enum_type  enum_value )

inlineconstexpr

Helper function that converts enum type to underlying integer type.

Note

This function may be removed after switching to C++23

Template Parameters

Enum_type

Type of the enumeration parameter that gets converted into the underlying type value
