pub fn propagate_inputs(
parent: &dyn Kernel,
child: &mut dyn Kernel,
) -> Result<(), WriteError>Expand description
Copy parent’s input values into child’s inputs of the same name:
what carries a cascade of externs down a scope tree past what the
child imports as outputs.
Coordinates are not copied; a host positions a child with
set_inputs. An input with no value on the parent is skipped. A
value the child’s declared input refuses is an error naming both,
not a skip (input_variance.md §7).
