std::stop_source::stop_source - cppreference.com (original) (raw)

stop_source(); (1) (since C++20)
explicit stop_source( std::nostopstate_t nss ) noexcept; (2) (since C++20)
stop_source( const stop_source& other ) noexcept; (3) (since C++20)
stop_source( stop_source&& other ) noexcept; (4) (since C++20)

Constructs a new stop_source object.

  1. Constructs a stop_source with new stop-state.

  2. Constructs an empty stop_source with no associated stop-state.

  3. Copy constructor. Constructs a stop_source whose associated stop-state is the same as that of other.

  4. Move constructor. Constructs a stop_source whose associated stop-state is the same as that of other; other is left empty.

[edit] Parameters

nss - an std::nostopstate_t placeholder object to construct an empty stop_source
other - another stop_source object to construct this stop_source object with

[edit] Postconditions

  1. stop_possible() is true and stop_requested() is false.

  2. stop_possible() and stop_requested() are both false.

  3. *this and other share the same associated stop-state and compare equal.

  4. *this has other's previously associated stop-state, and other.stop_possible() is false.

[edit] Exceptions

  1. std::bad_alloc if memory could not be allocated for the stop-state.
