Struct DisplayPort 

pub struct DisplayPort {
    pub value: ArenaIndex,
    pub port: PortId,
}

Write a Value through an IoProvider port.

This is a convenience for the evaluator’s display / write builtins to emit a value through the I/O abstraction without requiring alloc. The idx is an arena index that the caller can format into the port.

Implementations of higher-level display logic live in the evaluator (or in grift_std), but this marker type can carry the index through the trait boundary.

Fields

value: ArenaIndex

The arena index of the value to display.

port: PortId

The target port.
