Enum AmountSpec 

pub enum AmountSpec {
    Literal(i32),
    X,
    Svar(String),
}

The amount slot of a CostPart. Replaces the legacy i32 (with DYNAMIC_X_SENTINEL) once consumers are migrated. Mirrors Java’s CostPart.convertAmount + AbilityUtils.calculateAmount split: literals resolve trivially, X reads XPaid / SVar:X, named SVar identifiers walk the host card’s SVar table at call time.

Variants

Literal(i32)

X

Svar(String)

SVar name on the host card (e.g. Y in ExileFromHand<Y/Card.Blue> — the only legitimate source today is the RaiseCost SVar walker in cost_adjustment). Reserved for explicit, audited parser sites.

Implementations

impl AmountSpec

pub fn parse_or(raw: &str, default: i32) -> Self

Parse a script amount token ("3", "X"). Strips any trailing /extra suffix so DSL forms like Draw<1/You> parse as 1. Non-int, non-X tokens fall back to Literal(default) — Self::Svar is reserved for explicit parsers that want SVar-chain resolution (only cost_adjustment today).

pub fn resolve(&self, game: &GameState, source: CardId, player: PlayerId) -> i32

Resolve to an i32 at call time. X reads XPaid/SVar:X via the legacy resolve_dynamic_amount flow; Svar(name) walks the host’s SVar chain to its first numeric value.

pub fn as_literal(&self) -> Option<i32>

pub fn is_x(&self) -> bool
