Documentation
data UrlRequest Source #
A UrlRequest object contains a url to get, the file into which the contents at the given url should be written, the cachability of this request and the request's priority.
A UrlState object contains a map of url -> InProgressStatus, a Q of urls waiting to be started, the current pipe length and the unique junk to create unique filenames.
Constructors

Fields
| |
Q represents a prioritised queue, with two-tier priority. The left list contains higher priority items than the right list.
Constructors
| Q [a] [a] |
readQ :: Q a -> Maybe (a, Q a) Source #
readQ will try and take an element from the Q, preferring elements from
the high priority list.
addUsingPriority :: Priority -> a -> Q a -> Q a Source #
Return a function for adding an element based on the priority.
deleteQ :: Eq a => a -> Q a -> Q a Source #
deleteQ removes any instances of a given element from the Q.
data ConnectionError Source #
Data type to represent a connection error. The following are the codes from libcurl which map to each of the constructors: * 6 -> CouldNotResolveHost : The remote host was not resolved. * 7 -> CouldNotConnectToServer : Failed to connect() to host or proxy. * 28 -> OperationTimeout: the specified time-out period was reached.
