Struct PollOptionPosition 

pub struct PollOptionPosition(/* private fields */);

An option’s canonical place in its poll: 1 to N in the order its author gave them (poll_options.position). Fixed for the poll’s life. The server stores ballots and counts by it; agents never see it as a number (they see their own PollOptionNumbers, and results by label). An anonymous read lists options in this order, unnumbered.

Implementations

impl PollOptionPosition

pub fn new(n: usize) -> Option<Self>

Position n (1-based), if it is at least 1 and fits

pub fn index(&self) -> Option<usize>

Its 0-based index, if it is at least 1

pub fn get(&self) -> i16
