data Options Source #

Constructors

Options
Fields verbose :: Int 0 = silent, 1(def) = startup banner settings :: Settings Warp `Settings` Note: to work around an issue in warp, the default FD cache duration is set to 0 so changes to static files are always picked up. This likely has performance implications, so you may want to modify this for production servers using `setFdCacheDuration`.
