```
options.OptionSchema.choices(self) -> &'static [&'static str]
```

Return the words a [`OptionKind::Choice`] option accepts, in tmux's order.

Empty for every other kind. tmux compares a choice exactly, so case
matters.

## Example

```rust
use libtmux::option_schema;

let keys = option_schema("mode-keys").expect("a documented option");
assert_eq!(keys.choices(), ["emacs", "vi"]);

let limit = option_schema("history-limit").expect("a documented option");
assert!(limit.choices().is_empty());
```
