assertE :: Exception e => Bool -> e -> IO ()

This asserts that the provided Bool is True, throwing a provided exception is the argument was False.

noteE :: Exception e => Maybe r -> e -> IO r

This unwraps a Maybe value, throwing a provided exception if the value is Nothing.

hoistE :: Exception e => Either e r -> IO r

This unwraps an Either value, throwing the contained exception if the Either was a Left value.

(~=) :: String -> String -> Bool

Case Insensitive string comparison

withConnection :: ConnectionData -> (MMConn -> IO a) -> IO a

Creates a new connection to Hostname from an already initialized ConnectionContext.

mkConnection :: ConnectionContext -> Hostname -> Port -> Bool -> IO Connection

Creates a connection from a ConnectionData value, returning it. It is the user's responsibility to close this appropriately.

This function respects ALL_PROXY, HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables for controlling whether the resulting connection uses a proxy. However, note:

• Only SOCKS version 4 and 5 proxies are supported using socks4:// and socks5:// URIs, and
• No proxy authentication is supported.

connectionGetExact :: Connection -> Int -> IO ByteString

Get exact count of bytes from a connection.

The size argument is the exact amount that must be returned to the user. The call will wait until all data is available. Hence, it behaves like hGet.

On end of input, connectionGetExact will throw an isEOFError exception. Taken from: https://github.com/vincenthz/hs-connection/issues/9
