Struct FallbackSource 

pub struct FallbackSource { /* private fields */ }

Asks several sources in order and returns the release from the first one that answers: a mirror or a second host for when the primary is down.

The first source that answers wins, even when a later one knows a newer release; the sources are not compared. When every source fails, the error is the primary’s, and every failure is logged at warn.

Each source checks what it fetches with its own settings, such as a manifest’s signing keys. The engine checks the artifact with the same EngineConfig whichever source named it.

use gpui_updater_core::{FallbackSource, GitHubSource, StaticManifestSource};

let source = FallbackSource::new(StaticManifestSource::new(
    "https://updates.example.com/latest.json",
))
.or(GitHubSource::new("owner", "repo"));
