Module input 

What an event hands its handler, for the events whose payload is more than a value.

These are the Host’s types rather than an authoring layer’s, because what they hold is decided by the wire: a key press and whether it was consumed, the paths a drop carried, the range a list asked for. Every runtime hands the same ones over.

Structs

FileDrop

The paths of the files a reader let go over a node.

KeyEvent

A key-down event whose consumption state is shared with the Host boundary.

RangeRequest

The visible item range the Renderer asks the Host to materialise.
