std::execution::let_value
Defined in header <execution> | ||
|---|---|---|
execution::sender auto
let_value( execution::sender auto input,
std::invocable</*values-sent-by*/(input)...> function );
| (since C++26) |
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.
