let_value
Defined in header
<execution>
execution::sender auto
(since C++26)
let_value( execution::sender auto input,
[edit] 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
[edit] 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.
