Function exchange 

pub fn exchange(
    component: Component,
    binary: &Path,
    args: &[OsString],
    operation: &str,
    scope: &Operation,
) -> Result<Value, Error>

Receive a machine result while the component owns interactive input and live diagnostics.

Errors

Rejects cancellation, invalid replies, nonzero exits, oversized stdout and process failures.
