NAME¶

std::execution::let_value - std::execution::let_value

Synopsis¶

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 - sender which once executed sends the values upon which the function
executes
function - 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.
