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, or std::promise) can provide a std::future object to the creator of that asynchronous operation. the creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std. 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. if valid () is false before the call to this function, the behavior is undefined.

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 (), std::packaged task::get future () or std::async ()) until the first time get () or share () is called. the behavior is undefined if any member function other than the destructor, the move assignment operator, or valid is. Blocks until the result becomes available. valid() == true after the call. the behavior is undefined if valid() == false before the call to this function. To opt in to the future behavior, set `pd.set option('future.no silent downcasting', true)` 0 1 1 0 2 2 3 1 dtype: int64 if i understand the warning correctly, the object dtype is "downcast" to int64. perhaps pandas wants me to do this explicitly, but i don't see how i could downcast a string to a numerical type before the replacement happens. 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 scheduling or resource contention delays. the standard recommends that a steady clock is used to measure the duration.

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 may refer to the same shared state. access to the same shared state from multiple threads is safe if each thread does it through its own copy of a shared future object. If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting. the behavior is undefined if valid () is false before the call to this function, or clock does not meet the clock requirements. the programs is ill formed if std::chrono::is clock v<clock> is false.(since c 20). A future statement is a directive to the compiler that a particular module should be compiled using syntax or semantics that will be available in a specified future release of python. the future statement is intended to ease migration to future versions of python that introduce incompatible changes to the language. it allows use of the new features on a per module basis before the release in. Warning: restricted methods will be blocked in a future release unless native access is enabled i understand this relates to java's native access restrictions introduced in newer jdks.
