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_status
Specifies state of a future as returned by wait_for and wait_until functions of std::future and std::shared_future. Constants
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
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
9 Data-Backed Trends Shaping PV Module Costs to 2030

Solar Market Insight Report Q4 2025 – SEIA
Module prices have declined by 12% year-over-year, on average, across all segments. This dip was driven by the expansion of manufacturing capacity and higher module power output as
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,

Spring 2025 Solar Industry Update
Global polysilicon spot prices rose 12% in Q1 2025, from $5.54/kg to $6.24/kg. In Q4 2024, the average U.S. module price ($0.28/Wdc) was down 3% q/q and about three times higher
Global Market Outlook for Solar Power 2025-2029
Cumulative solar PV capacity is expected to exceed most energy analysts'' forecasts by 2030. If the solar market trajectory continues as projected, total global solar installations are set to
Empirical approach shows PV is getting cheaper than

Mockito is currently self-attaching to enable the inline-mock-maker
I get this warning while testing in Spring Boot: Mockito is currently self-attaching to enable the inline-mock-maker. This will no longer work in future releases of the JDK. Please add
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 (),
6 Projections for Solar Panel Pricing Through 2030
