fn node_pins_in(&self, registry: &Registry) -> Vec<NodePin<Self::TypeInfo>>

fn node_pins_out(&self, registry: &Registry) -> Vec<NodePin<Self::TypeInfo>>

fn node_is_start(&self, registry: &Registry) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
