Function Documentation

◆ operator<<() [1/2]

std::ostream & operator<<	(	std::ostream &	os,
		const tenant_id &	id
	)

Stream insertion operator for tenant_id.

Parameters

os	The output stream.
id	The tenant_id to output.

Returns: The output stream.

◆ operator<<() [2/2]

std::ostream & operator<<	(	std::ostream &	os,
		const std::optional< tenant_id > &	id
	)

Stream insertion operator for optional tenant_id.

Parameters

os	The output stream.
id	The optional tenant_id to output.

Returns: The output stream.

Variable Documentation

◆ nil_uuid_str

constexpr char nil_uuid_str[] = "00000000-0000-0000-0000-000000000000"

constexpr

String representation of the nil UUID (all zeros).

The nil UUID is the default value for a default-constructed boost::uuids::uuid. This constant is used to detect uninitialized or legacy tenant IDs.

◆ max_uuid_str

constexpr char max_uuid_str[] = "ffffffff-ffff-ffff-ffff-ffffffffffff"

constexpr

String representation of the max UUID (all ones).

The max UUID is defined in RFC 9562 as a sentinel value. It is used as the system tenant identifier because it cannot be accidentally created through default construction.
