param_as_string()

stdx::expected< std::string, std::error_code > param_as_string

(

const classic_protocol::borrowed::message::client::Query::Param &

param

)

convert a string-typed query param to a std::string.

• BLOB
• TEXT
• STRING
• VARCHAR
• VARSTRING

are string-types.

• returns std::errc::bad_message if a non-string type is provided
• returns a codec_errc if decoding the parameter fails.

Parameters

param

parameter of a query attribute

Returns

a std::string on success, a std::error_code on error.

param_to_number()

stdx::expected< uint64_t, std::error_code > param_to_number

(

const classic_protocol::borrowed::message::client::Query::Param &

param

)

convert a numeric type into an unsigned integer.

param_to_string()

stdx::expected< std::string, std::error_code > param_to_string

(

const classic_protocol::borrowed::message::client::Query::Param &

param

)

convert any param-type into a human readable string.
