data Settings

Various Warp server settings. This is purposely kept as an abstract data type so that new settings can be added without breaking backwards compatibility. In order to create a Settings value, use defaultSettings and the various 'set' functions to modify individual fields. For example:

setTimeout 20 defaultSettings

Fields

settingsPort :: Int

Deprecated: Use setPort instead

Port to listen on. Default value: 3000

Default: 500, text/plain, "Something went wrong"

Since 2.0.3

settingsOnOpen :: SockAddr -> IO Bool
