Module wire 

Scenes and their edits on the wire: a scene to its proto::Scene and back, and Edits to the proto::Patch the watch stream sends and back (patch). Each image file and font file travels once: a scene carries every one its nodes use, a patch only those the scene before it didn’t have. It does no I/O.

Functions

apply

Applies a patch to scene, whose files uses counts, as a browser holding the scene does — or says why it can’t, leaving both as they were.

decode

A node from the wire, or why it isn’t one.

decode_scene

The scene a stream message carries; image and font files held already has aren’t decoded or checked again.

encode

encode_own

A node’s own attributes for the wire: its children aside.

patch

edits as a patch.

scene

A whole scene for the wire: its tree and every image file it shows.
