Create a error catcher for common errors which displays useful information
When the users of the karrieredag hit a bug, they will most likely get a 500
type error which says Internal server error
. This is not really a great user experience. We should add a error catcher which renders a page with contact information (e.g. login email) and with a prompt to send a email there if the problem persists.
See https://rocket.rs/v0.4/guide/requests/#error-catchers for more information about creating catchers
in rocket
.
