// Example 10 — Static Hello Pipeline
|
|
//
|
|
// The same linear pipeline as example 01, built with make_network() instead
|
|
// of the runtime Network builder. The topology is fully known at compile time:
|
|
// cycle detection is a static_assert, no build() step is needed, and start/stop
|
|
// require no virtual dispatch through a string-keyed node map.
|
|
//
|
|
// [produce] --int--> [double_it] --int--> [print_it]
