Future With B Tech Cse In Artificial Intelligence Machine Learning

M Tech Cse Artificial Intelligence Machine Learning Pdf 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. 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.

I was wondering when i should use the future builder. for example, if i want to make an http request and show the results in a list view, as soon as you open the view, should i have to use the future. Here are some other differences: futurebuilder has a single asyncsnapshot that represents the current state of the future, while streambuilder has multiple asyncsnapshots, each representing a new piece of data emitted by the stream. 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.

The return type of std::async is std::future, where v is: the call to std::async synchronizes with the call to f, and the completion of f is sequenced before making the shared state ready. 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 wait until returned. 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. This future feature is also missing in python 3.6. why isn't it back ported? if i use annotations, they are widely supported in 3.7, so no need for a future. if i run my code on an older python, both, the annotations and the future are not supported. so why this future?.
