UUID value exposed through multiple integer views.

Member Function Documentation

generate() [1/2]

uuid_t uuid_util::uuid_t::generate ( )

inlinestatic

Generate a UUID value.

Returns

Random UUID generated from std::random_device seeding.

generate() [2/2]

uuid_t uuid_util::uuid_t::generate ( std::default_random_engine & engine )

inlinestatic

Generate UUID bytes and apply the established version and variant masks.

Parameters

engine

Random-number engine used to generate UUID bytes.

Returns

Random UUID generated from the supplied engine.

operator<()

bool uuid_util::uuid_t::operator< ( const uuid_t & other ) const

inlineconstexpr

Order UUID values by their 64-bit word representation.

Parameters

other

UUID value to compare against.

Returns

True when this UUID sorts before other.

operator==()

bool uuid_util::uuid_t::operator== ( const uuid_t & other ) const

inlineconstexpr

Compare two UUID values for equality.

Parameters

other

UUID value to compare against.

Returns

True when both UUID values contain identical bytes.

operator>()

bool uuid_util::uuid_t::operator> ( const uuid_t & other ) const

inlineconstexpr

Order UUID values by their 64-bit word representation.

Parameters

other

UUID value to compare against.

Returns

True when this UUID sorts after other.

string()

std::string uuid_util::uuid_t::string ( ) const

inlinenodiscard

Format the UUID using canonical text form.

Returns

Canonical lowercase UUID string.
