-;; Usage:
-;; (require 'flymake-rust)
-;; (add-hook 'rust-mode-hook 'flymake-rust-load)

-;; If you want to use rustc compiler, you must add following string:
-;; (setq flymake-rust-use-cargo 1)
-;;
-;; Uses flymake-easy, from https://github.com/purcell/flymake-easy
-
-;;; Code:
-
-(require 'flymake-easy)
-
-(defconst flymake-rust-err-line-patterns
- '(("^\\(.*\\)\n --> \\(.*.rs\\):\\([0-9]+\\):\\([0-9]+\\)$" 2 3 4 1)
- ("^\\(.*.rs\\):\\([0-9]+\\):[0-9]+: [0-9]+:[0-9]+ [a-z]+: \\(.*\\)$" 1 2 nil 3)
- ("^\\(.*.rs\\):\\([0-9]+\\) \\(.*\\)$" 1 2 nil 3)))

-(setq-default flymake-rust-use-cargo 1)

-(if flymake-rust-use-cargo
- (defvar flymake-rust-executable "cargo"
- "The rust executable to use for syntax checking.")
- (defvar flymake-rust-executable "rustc"
- "The rust executable to use for syntax checking.")
-)
-
-;; Invoke rust "--parse-only" to get syntax checking
-(defun flymake-rust-command (filename)
- "Construct a command that flymake can use to check rust source."
- (if flymake-rust-use-cargo
- (list flymake-rust-executable "build")

-;; Load rust-flymake
-(defun flymake-rust-load ()
- "Configure flymake mode to check the current buffer's rust syntax."
