Struct Port 

pub struct Port {
    pub id: String,
    pub label: String,
    pub direction: PortDirection,
    pub port_type: String,
    pub color: Option<String>,
}

A typed input or output port on a node. Ports define connection points — edges connect from an output port to an input port.

Fields

id: String

Unique identifier within the node (e.g., “message”, “response”).

label: String

Display label.

direction: PortDirection

Whether this is an input or output port.

port_type: String

Type tag for connection compatibility (e.g., “text”, “json”, “tool_call”). Only ports with matching types can be connected.

color: Option<String>

Optional color override for the port dot.
