Struct PackageSpec 

pub struct PackageSpec {
    pub app_name: &'static str,
    pub on_installed: Option<fn()>,
    pub on_uninstalling: Option<fn()>,
    pub before_apply: Option<fn() -> Result<(), String>>,
    pub cli: Option<CliSpec>,
    pub services: Services,
}

What a package needs from the app.

Fields

app_name: &'static str

The app’s directory name, where the last version run is kept: sapphire-journal.

on_installed: Option<fn()>

Run once per install: in the install hook on Windows, at the first start elsewhere. It must be safe to run again.

on_uninstalling: Option<fn()>

Run before uninstalling, on Windows only (no other OS runs anything): 30 seconds, no window.

before_apply: Option<fn() -> Result<(), String>>

Run before any update is applied: stop the app’s background processes. An error stops the update.

cli: Option<CliSpec>

The command line to put on PATH, if the app has one.

services: Services

The app’s background services: the running ones are stopped before an update is applied and started again at the next start, and on Windows each is uninstalled with the app. An app without services writes Services::NONE.
