Struct Downloader 

pub struct Downloader { /* private fields */ }

Unified downloader — sole HTTP client owner and fetch orchestrator.

Created once at the application level, then shared (via Clone) across protocol configs. Owns the HttpClient and the runtime handle. Protocols obtain a PeerHandle via register and issue fetches through PeerHandle::execute.

Implementations

impl Downloader

pub fn new(config: DownloaderConfig) -> Self

Create a new downloader from configuration.

Adopts config.client (a clone of the caller’s HttpClient) and the shared AbrController from config.abr_settings.

pub fn register(&self, peer: Arc<dyn Peer>) -> PeerHandle

Register a peer and return its PeerHandle.

Double-registers the peer: fetch channel through the download loop and ABR state through the shared controller. The returned handle’s Drop unregisters both.
