nbari / cron-parser

I got error when i parse wrong cron expression: * * * *

index out of bounds: the len is 4 but the index is 4

And i found this line try to get field by index 4:

Line 187 in 37500d2

let do_w = parse_field(fields[4], 0, 6)?;

Then i found these line checked if number of fields greater than 5, will throw a error:

Lines 123 to 125 in 37500d2

    
           if fields.len() > 5 { 
        
               return Err(ParseError::InvalidCron); 
        
           }

Should we throw a error if number of fields less than 4? Like this:

if fields.len() != 5 {
    return Err(ParseError::InvalidCron);
}

Hi @LemonNekoGH, many thanks, fixed 👍

Program panicked when number of fields less than 5
