tauri-plugin-hdiff-update

Tauri v2 plugin for signed HDiffPatch differential installer updates.

Install

[dependencies]
tauri-plugin-hdiff-update = "0.1"

Register the plugin:

tauri::Builder::default()
    .plugin(tauri_plugin_hdiff_update::init())

Enable the production permission set:

"hdiff-update:default"

The default permission only exposes the production update path:
