Struct Updater 

pub struct Updater { /* private fields */ }

The app-level updater: an UpdateConfig plus the parts only the UI side needs — the poll cadence, the update window’s title, and hooks for posting a notification and for saving state before the app restarts.

let updater = Updater::github("Acme", env!("CARGO_PKG_VERSION"), "acme/acme")
    .codesign_requirement("anchor apple generic and certificate leaf[subject.OU] = XJDC46F35X")
    .before_restart(|cx| save_session(cx));
guise::update::start(updater, cx);

Implementations

impl Updater

pub fn new( app: impl Into<String>, version: impl Into<String>, source: UpdateSource, ) -> Self

An updater for app at version, checking source.

pub fn github( app: impl Into<String>, version: impl Into<String>, repo: impl Into<String>, ) -> Self

An updater reading a GitHub repo’s releases/latest, given owner/repo.

pub fn from_config(config: UpdateConfig) -> Self

Wrap an existing UpdateConfig.

pub fn require_checksum(self, require: bool) -> Self

See UpdateConfig::require_checksum — recommended for Linux installs, which have no signature to fall back on.

pub fn codesign_requirement(self, requirement: impl Into<String>) -> Self

See UpdateConfig::codesign_requirement — required for macOS installs.

pub fn user_agent(self, user_agent: impl Into<String>) -> Self

Override the User-Agent sent with every request.

pub fn slug(self, slug: impl Into<String>) -> Self

Override the filesystem-safe name used for staging paths.

pub fn poll_every(self, every: Duration) -> Self

How often super::start re-checks while the app runs (default one hour).

pub fn window_title(self, title: impl Into<SharedString>) -> Self

Title for the windows super::check_now opens (default “Software Update”, the platform convention).

pub fn on_notify(self, notify: impl Fn(&str, &str) + 'static) -> Self

Called with (title, body) when the install starts, finishes without a window to restart into, or fails. guise never posts an OS notification itself — that needs an app’s own bundle identity and permission state.

pub fn before_restart(self, hook: impl Fn(&mut App) + 'static) -> Self

Called immediately before the app restarts into the new version — the place to persist a session, since the restart never goes through the normal quit path where an app would usually save.

pub fn config(&self) -> &UpdateConfig

The Send half, for the background check and install.

pub fn app(&self) -> &str

The app’s display name.

pub fn version(&self) -> &str

The running version.

pub fn poll(&self) -> Duration

The re-check cadence.

pub fn title(&self) -> &SharedString

The update window’s title.

impl Clone for Updater

fn clone(&self) -> Updater

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
