Detailed Description

An AMQP message ID.

It can contain one of the following types:


Friends And Related Function Documentation

uint64_t get< uint64_t > ( const message_id x  )  [related]

Get the uint64_t value or throw conversion_error.

uuid get< uuid > ( const message_id x  )  [related]

Get the uuid value or throw conversion_error.

binary get< binary > ( const message_id x  )  [related]

Get the binary value or throw conversion_error.

std::string get< std::string > ( const message_id x  )  [related]

Get the std::string value or throw conversion_error.

T coerce ( const message_id x  )  [related]

Coerce the contained value to type T. For example:uint64_t i = coerce<uint64_t>(x)This will succeed if x contains any numeric value, but may lose precision if it contains a float or double value.

Exceptions:
conversion_error if the value cannot be converted to T according to `stdis_convertible`
