Enum WorkerAssets 

pub enum WorkerAssets<'a> {
    Deployed(&'a str),
    PerComponent {
        cdn_base: &'a str,
        env: &'a str,
    },
    Unplaced,
}

How the Worker arm resolves a static route’s origin (R898-T4).

Two shapes because the Worker arm is configured from two sources that differ in exactly this: a mirror’s static slot carries ONE deployed asset_origin field, while a domain manifest carries a component ref per route. Collapsing both to the deployed string is what made a second static route meaningless — every entry would resolve to the same origin, which is plan_domain_worker’s find_map-the-first defect wearing a table.

Variants

Deployed(&'a str)

Every static route serves from this one origin — the mirror-driven path, where the slot’s asset_origin field IS the answer.

PerComponent

Each static route serves from its own component’s published prefix. The alias tier (R561-F3), and the several-buckets-behind-one-domain case R560-F13 asked for: the routes name different services, so they resolve to different origins.

Fields

cdn_base: &'a str

The tier’s CDN origin, e.g. https://cdn.net.yah.dev.

env: &'a str

Mirror env the publisher wrote under, e.g. prod.

Unplaced

No CDN tier is known — a manifest-only Worker deployed by the domain pass (R560-F13). A component static route has no origin under this and the compile refuses it naming the route; bucket, backend and redirect routes need no asset placement and compile as usual.

Implementations

impl WorkerAssets<'_>

pub fn fallback_origin(&self, domain: Option<&DomainConfig>) -> Option<String>

The ASSET_ORIGIN binding value: where a path that NO table entry claims is fetched from.

For Self::Deployed that is the deployed origin, domain or no domain. For Self::PerComponent it is the FIRST static route’s origin — not because first-wins is back, but because ASSET_ORIGIN is a single binding and a domain with a static catch-all resolves it to the same string either way. Every static route still gets its own entry in the table, which is what the door actually matches on.

None means no path falls through to an HTTP asset origin: no domain, no component static route (bucket routes read through R2 bindings, not an origin), a static route whose component ref is malformed, or Self::Unplaced.

Self::Deployed is returned VERBATIM, trailing slash and all, while RoutePlacement::asset_origin trims it for the table. That asymmetry is deliberate and load-bearing: the ASSET_ORIGIN binding is a live deployed value read off a mirror’s static slot, and R898-T4 is not the change that quietly renormalizes it under every Worker on the fleet.
