Panic will stop program at place of error, while I want nicely stacked error message list: [reports.rs:25] ERROR: Cannot write report "Foo" to file "foo.xml". [templates.rs:125] ERROR: Cannot process template "header". Check is template file exists and readable. [fileio.rs:45] ERROR: Cannot open file "/usr/share/foo/templates/header.tmpl": unable to enter directory "/usr/share/foo". Check directory permissions. Instead of writing report cannot open file done It saves lot of time(money) in production.
