Required Methods

fn from_core(core: Ref<DownloadInstance>) -> Self

Construct the object now that the core object has been created.

fn handle(&self) -> Ref<DownloadInstance>

Get the core object, typically the handle is stored directly on the object.

fn perform_custom_request<I>( &self, method: &str, url: &str, headers: I, ) -> Result<DownloadResponse, String>

where I: IntoIterator<Item = (String, String)>,

Send an HTTP request on behalf of the caller.

The caller will expect you to inform them of progress via the following:

• DownloadInstance::read_callback
• DownloadInstance::write_callback
• DownloadInstance::progress_callback

Provided Methods

fn new_with_provider( provider: DownloadProvider, ) -> Result<Ref<DownloadInstance>, ()>

fn perform_request(&self, url: &str) -> Result<(), String>

Send an HTTP request on behalf of the caller.

The caller will expect you to inform them of progress via the following:

• DownloadInstance::read_callback
• DownloadInstance::write_callback
• DownloadInstance::progress_callback
