Rushterm
Create nested menus on the terminal, navigate with hotkeys. Data-driven. No function/macro complexity.
Example
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 chain .print()
and .run()
methods on the instance to execute our menu:
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."),
};
let selection = menu.print().run();
dbg!(&selection);
}
If selection is successful, run()
method will return us a Selection
type in Ok()
variant to get information we may need in ongoing execution. If not, exits the execution with an Err()
variant.
