Trait PortReaderT 

pub trait PortReaderT {
    // Required method
    fn port(&self, name: &str) -> Option<Value>;
}

The COVERED-path port accessor (bc#94): the by-name read a combined handler uses, WITHOUT the dynamic PortReader::as_any downcast hook. The generated combined runner passes each node’s CONCRETE ports struct to the handler by direct generic instantiation (&P where P: PortReaderT, monomorphized per node) — never behind &dyn, never via as_any/downcast. A PortReaderT handler still reads a port by name (boxing that one field on demand) if it does not want to name the concrete struct type, but the SEAM itself carries no dyn/as_any: the concrete type flows through monomorphization. (PortReader — with as_any — stays for the UNCOVERED NativeComponentExec path, retired later.)

Required Methods

fn port(&self, name: &str) -> Option<Value>

The Value for a port name, and whether it is a declared port of this node.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
