Struct Choice 

pub struct Choice {
    pub text: String,
    pub index: usize,
    pub tags: Vec<String>,
    pub sticky: bool,
    pub source: Option<SourceLocation>,
}

A single choice presented to the player.

Fields

text: String

index: usize

Position among the choices presented — the value [Story::choose] takes. Numbers the visible choices contiguously (an invisible fallback never occupies a slot), matching C#’s Choice.index / ChooseChoiceIndex (issue #3527).

tags: Vec<String>

sticky: bool

+ (sticky, offered again) vs * (once-only) in the source — the bytecode’s ChoiceFlags::once_only, inverted. A host that echoes the taken choice can mark it the way it was written (#3435).

source: Option<SourceLocation>

Where the choice’s text came from in the author’s source (#3435) — the first LineRef of the choice’s display fragment, the same rule OutputLine::source uses. None when the display is not a fragment (a constant string, an empty label) or the line table carries no location.
