Function tectonic_bundles::get_fallback_bundle

pub fn get_fallback_bundle(
    format_version: u32,
    only_cached: bool,
    status: &mut dyn StatusBackend
) -> Result<CachingBundle<IndexedTarBackend>>

Open the fallback bundle.

This is essentially the default Tectonic bundle, but the higher-level tectonic crate provides a configuration mechanism to allow the user to override the bundle URL setting, and that should be preferred if you’re in a position to use it.
