std::execution::let_value(3)

🌸 NAME 🌸

Hiii bestie!! 💖 This is std::execution::let_value(3), folded in from the C++ Standard Libary manual (yes, that’s the manual name — spelling and all, no cap).

std::execution::let_value - std::execution::let_value — yep, the name is the name, iconic. 👑

✨ Synopsis ✨

Okay so here’s the signature in all its glory, bestie:

Defined in header <execution>
execution::sender auto let_value(

    execution::sender auto input,                      (since C++26)
    std::invocable<values-sent-by(input)...> function

);

🎀 Parameters 🎀

• input — a sender which once executed sends the values upon which the function executes. 💅
• function — an invocable to be called with the values from the input sender. 🫶

👑 Return value 👑

Returns a sender describing the task graph described by the input sender, with an added node of invoking the provided function with the values sent by the input sender as arguments. 🌟

let_value is similar to then, however, where the sender returned from then sends exactly what that function ends up returning — let_value requires that the function returns a sender, and the sender returned by let_value sends the values sent by the sender returned from the callback. Periodt. 💅🔥
