Expand description

Platform implementation for update discovery and package installation.

Provided Methods§

Source

fn capabilities(&self) -> AppUpdateCapabilities

What this backend can do.

Defaults to neither, so a backend states what it can do rather than inheriting a claim: the two entry points below refuse a half a backend has not claimed, and a backend that forgot to declare one is refused rather than allowed to fail at the platform boundary.

Source

fn check(&self, source: &GitHubReleaseUpdate) -> Result<(), AppUpdateError>

Starts release discovery. Progress is published through set_app_update_status.

Source

fn install(&self, package: &UpdatePackage) -> Result<(), AppUpdateError>

Transfers a package to the platform installer.

An implementation checks the package against UpdatePackage::digest before committing it — nothing is installed whose bytes were not the ones the release feed promised.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
