Trait PortField 

pub trait PortField {
    type Iface: ?Sized + 'static;

    // Required methods
    fn slot_any(&self) -> Rc<dyn Any>;
    fn bound(&self) -> bool;
}

The bridge between a port field and the generated ComponentNode methods.

The derive sees the field’s type text (PutPort<u32>), not its meaning, so it names the interface as <PutPort<u32> as PortField>::Iface rather than parsing generics out of tokens.

Required Associated Types

type Iface: ?Sized + 'static

The interface this port demands: dyn PutIf<T>, dyn GetIf<T>, …

Required Methods

fn slot_any(&self) -> Rc<dyn Any>

The binding cell, erased, so connect can reach it through dyn.

fn bound(&self) -> bool

Has it been connected?

Dyn Compatibility

This trait is dyn compatible.

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