std::future<T>::~future
Releases any shared state. This means: If the current object holds the last reference to its shared state, the shared state is destroyed. The current object gives up its reference to its shared
std::future<T>::valid
Checks if the future refers to a shared state. This is the case only for futures that were not default-constructed or moved from (i.e. returned by std::promise::get_future (),
Current Status and Future Development Trend of Solar
This paper presents the current status of solar photovoltaic (PV) power generation, delving into its advantages and limitations. Solar PV systems convert light energy into electricity through light
Executive summary – Renewables 2025 – Analysis
Solar PV accounts for almost 80% of the global increase, followed by wind, hydropower, bioenergy and geothermal. In more than 80% of countries
Ansible yum throwing future feature annotations is not defined
The error: SyntaxError: future feature annotations is not defined usually related to an old version of python, but my remote server has Python3.9 and to verify it - I also added it in my
Current Status and Future Direction of Photovoltaics
This paper provides an overview of the current status of photovoltaics and discusses future directions for photovoltaics from the view
std::future<T>::wait_for
If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. This function may block for longer than timeout_duration due to
The Future of Solar Energy in 2025 and Beyond
As we approach a transformative period for the energy industry, The Future of Solar Energy in 2025 and Beyond signals a pivotal shift toward a
std::future<T>::wait_until
wait_until waits for a result to become available. It blocks until specified timeout_time has been reached or the result becomes available, whichever comes first. The return value indicates why
std::future<T>::get
The get member function waits (by calling wait ()) until the shared state is ready, then retrieves the value stored in the shared state (if any). Right after calling this function, valid () is false.
std::shared_future
Unlike std::future, which is only moveable (so only one instance can refer to any particular asynchronous result), std::shared_future is copyable and multiple shared future objects
Future of Solar Energy 2026–2035: Technology Trends, Costs
The future of solar energy through 2035 is defined by several compounding trends that individually represent significant shifts — and collectively represent a transformation of the energy
std::future_status
Specifies state of a future as returned by wait_for and wait_until functions of std::future and std::shared_future. Constants
The Future of Solar Energy | MIT Energy Initiative
The Future of Solar Energy considers only the two widely recognized classes of technologies for converting solar energy into electricity — photovoltaics (PV) and concentrated solar power (CSP),
The Future of Solar Energy: Solar Energy Trends 2025
Explore the future of solar in 2025—key trends, new tech, and policies driving global clean energy growth.
Standard library header <future> (C++11)

std::future
The class template std::future provides a mechanism to access the result of asynchronous operations: An asynchronous operation (created via std::async, std::packaged_task,
A review of solar photovoltaic technologies: developments, challenges
This review examines the evolution, current advancements, and future prospects of PV systems, highlighting the development of various photovoltaic cell technologies, including crystalline
Center for a Solar Powered Future (SPF2050)
At the end of their life, massive installations of solar cells will need to be recycled—a circular solar power economy must be created. Land use becomes a major challenge and creative, new approaches to
