Function defaultFetchBlob

defaultFetchBlob(
    sha256: string,
    servers: readonly string[],
    fetchImpl?: {
        (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
        (input: string | URL | Request, init?: RequestInit): Promise<Response>;
    },
): Promise<Uint8Array<ArrayBufferLike>>
Fetch an artifact blob by trying each server in turn with a 20-second budget.

Bytes are returned unverified; resolveNapplet hashes them. Gateways are accelerators, never identity.
Parameters
- sha256: string
  The blob hash, lowercase hex.
- servers: readonly string[]
  Server base URLs from the manifest.
- fetchImpl: {
  (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
  (input: string | URL | Request, init?: RequestInit): Promise<Response>;
  } = fetch
  The fetch to use; the global one by default.
  - (input: URL | RequestInfo, init?: RequestInit): Promise<Response>
