Member Function Documentation

act()

Activity & nix::curlFileTransfer::TransferItem::act ( )

inline

Lazily start an Activity. We don't do this in the TransferItem constructor to avoid showing downloads that are only enqueued but not actually started.

Member Data Documentation

acceptRanges

bool nix::curlFileTransfer::TransferItem::acceptRanges

Whether we can use range downloads for retries.

active

bool nix::curlFileTransfer::TransferItem::active

Whether the handle has been added to the multi object.

done

bool nix::curlFileTransfer::TransferItem::done

Whether either the success or failure function has been called.

enqueued

bool nix::curlFileTransfer::TransferItem::enqueued

Whether the request has been added the incoming queue.

hasContentEncoding

bool nix::curlFileTransfer::TransferItem::hasContentEncoding

Whether the response has a non-trivial (not "identity") Content-Encoding.

paused

bool nix::curlFileTransfer::TransferItem::paused

Whether the request has been paused previously.
