Make your CLI app easy by adding menu. Create nested menus, navigate with hotkeys. Data-driven. No function/macro complexity.
Firstly, we'll need to construct a Menu instance. Bring Menu and necessary sub types into scope. Menu instance doesn't need to be mutable. Next, we'll invoke .run() method on the instance to execute our menu:
```rust
use rushterm::{Action, Item, Menu, SubMenu};
fn main() {
let menu = Menu {
name: "My Main Menu",
items: vec![
Item::Action(Action {
name: "Action0",
hotkey: Some('a'),
exp: Some("Action0 Explanation. This Has Been Assigned To A Hotkey."),
}),
Item::Action(Action {
name: "Action1",
hotkey: None,
exp: Some("Action1 Explanation. This Has No Hotkey."),
}),
Item::SubMenu(SubMenu {
name: "Submenu0",
hotkey: Some('s'),
exp: Some("Submenu0 explanation."),
items: vec![
Item::Action(Action {
name: "Sub0 Action0",
hotkey: Some('a'),
exp: Some("Sub Action0 Explanation. This Has Been Assigned To A Hotkey."),
}),
Item::SubMenu(SubMenu {
name: "Deepermenu0",
hotkey: Some('d'),
exp: Some("Deepermenu0 Explanation."),
items: vec![
Item::Action(Action {
name: "Deeper Action0",
hotkey: Some('f'),
exp: None,
}),
Item::Action(Action {
name: "Deeper Action1",
hotkey: Some('g'),
exp: Some("Deeper Action1 Explanation."),
}),
],
}),
],
}),
],
exp: Some("My Main Menu Explanation."),
exit: true,
};
let selection = menu.run();
dbg!(&selection);
}
``
If selection is successful,run()method will return us aSelectiontype inOk()variant to get information we may need in ongoing execution. If not, exits the running with anErr()` variant.
