Macros to reduce the syntactic burden of parsing events about crossterm

[babybabycloud]

Maybe I have the same question, I didn't find a better solution to replace the below code

match key_event.code {
KeyCode::Char('A') => some_funtion('A'),
KeyCode::Char('B') => some_funtion('B'),
KeyCode::Char('C') => some_funtion('C'),
KeyCode::Char('D') => some_funtion('D'),
KeyCode::Char('E') => some_funtion('E'),
_ => (),
}

Although they all have the same logic, but I need to do the same thing for they all

you can match on variable no?

enum KeyCode{
    Char(char)
}
fn some_funtion(a: char) {
    
}

fn main() {
   match KeyCode::Char('b') {
    KeyCode::Char(c) => some_funtion(c),
    _ => (),
    }
}

For the macros i am not sure. Surely it removes redundancy, but the thing is that they are quite hard to understand on how to use them.

Yes, I think this is correct. After comment on this issue, I found such usage in other project. LOL
