"warning[...]: ..." style compile messages not recognized

[ensc]

Recent cargo clippy generates warnings like

warning[E0133]: call to unsafe function `....` is unsafe and requires unsafe block
  --> src/device.rs:43:2

rustic expects only warning: but not the tagged warning[E0133]:

rustic/rustic-compile.el

Lines 138 to 145 in e77f62f

	(defvar rustic-compilation-warning
	(let ((warning "^warning:[^\n]*\n\s*-->\s")
	(file "\\([^\n]+\\)")
	(start-line "\\([0-9]+\\)")
	(start-col "\\([0-9]+\\)"))
	(let ((re (concat warning file ":" start-line ":" start-col)))
	(cons re '(1 2 3 1)))) ;; 1 for warning
	"Create hyperlink in compilation buffers for rust warnings.")

and does not detect this as an actionable line. Regex should be changed to

  (let ((warning "^warning[^:]*:[^\n]*\n\s*-->\s")

(like for error)
