Macro routes 

macro_rules! routes {
    ( $s:expr ) => { ... };
    ( $inject:expr; $s:expr ) => { ... };
    ( $s:expr, $( $x:expr ),* ) => { ... };
    ( $inject:expr; $s:expr, $( $x:expr ),* ) => { ... };
}

Helper macro to chain multiple routes with .or(route()) between them.

Example - single use with data injection

struct DbConnection;
fn display_user(#[data] user: DbConnection) {}
let db_connection = DbConnection;
assert_eq!(routes![db_connection; display_user], display_user(db_connection));

Example - Multiple routes

fn info() {}
fn ping() {}
assert_eq!(routes![ping, info], ping().or(info()));

Example - Multiple routes with data injection

struct DbConnection;
fn display_user(#[data] db: DbConnection) {}
fn display_users(#[data] db: DbConnection) {}
let db_connection = DbConnection;
assert_eq!(routes![db_connection; display_user, display_users], display_user(db_connection).or(display_users(db_connection)));

Example - Multiple routes chaining with data injection

struct DbConnection;
fn ping() {}
fn info() {}
fn display_user(#[data] db: DbConnection) {}
let db_connection = DbConnection;
assert_eq!(routes![ping, info].or(routes![db_connection; display_user]), ping().or(info()).or(display_user(db_connection)));
