- std::future - cppreference. com
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
- std::shared_future - cppreference. com
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
- python - how to insert from __future__ import annotations in a future . . .
However, this is many years in the future, giving affected decorators plenty of time to update their code Make the future import a no-op in the future: Instead of eventually making from __future__ import annotations a SyntaxError, we could make it do nothing instead at some point after Python 3 13 reaches its end-of-life
- std::promise lt;R gt;::get_future - cppreference. com
Returns a future object associated with the same shared state as *this An exception is thrown if *this has no shared state or get_future has already been called To get multiple "pop" ends of the promise-future communication channel, use std::future::share
- Pandas replace and downcasting deprecation since version 2. 2. 0
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
