Struct Position 

pub struct Position {
    pub number: usize,
    pub current: usize,
    pub last: usize,
    pub duplicate: bool,
}

What a message needs from the list around it: its index number for ~m and whether its Message-ID repeats for ~=. Matching without a list (a single color rule, say) leaves this at its default, where both terms are false.

Fields

number: usize

1-based number as shown in the index; 0 when not on screen.

current: usize

The selected message’s number, for ..

last: usize

The last message’s number, for $.

duplicate: bool
