2024年3月12日 · 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.

2024年2月22日 · 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).

2021年8月27日 · 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.

2023年10月23日 · The promise is the "push" end of the promise-future communication channel: the operation that stores a value in the shared state synchronizes-with (as defined in std::memory_order) the successful return from any function that is waiting on the shared state (such as std::future::get).

When I run the program, Pandas gives 'Future warning' like below every time. D:\Python\lib\site-packages\pandas\core\frame.py:3581: FutureWarning: rename with inplace=True will return None from pandas 0.11 onward " from pandas 0.11 onward", FutureWarning) I got the message, but I just want to stop Pandas showing such message again and again.

2023年10月23日 · 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.

2021年1月22日 · Look at the Temporarily Suppressing Warnings section of the Python docs:. If you are using code that you know will raise a warning, such as a deprecated function, but do not want to see the warning, then it is possible to suppress the warning using the catch_warnings context manager:

I am using PowerShell and am trying to run the following command: .\\test_cfdp.exe < test.full | tee test.log test.full is a script that mimics command line inputs to test_cfdp.exe. However, I...

2011年2月26日 · To ensure future-proofing your query for SQL Server 2008 and higher, Date should be escaped because it's a reserved word in later versions. Bear in mind that the dates without times take midnight as their defaults, so you may not have the correct value there.
