Usage
extern crate trek_router;
use trek_router::Router;
type F = fn() -> usize;
let mut router = Router::<F>::new();
// scope v1
router.scope("/v1", |v1| {
v1.get("/login", || 0);
v1.post("/submit", || 1);
v1.delete("/read", || 2);
});
// scope v2
router.scope("/v2", |v2| {
v2.get("/login", || 0);
v2.post("/submit", || 1);
v2.delete("/read", || 2);
});
router.get("/foo", || 3);
router.post("/bar", || 4);
router.delete("/baz", || 5);
