Struct AttackingBand 

pub struct AttackingBand {
    pub attackers: Vec<CardId>,
    pub blocked: Option<bool>,
}

A band of attacking creatures. Mirrors Java’s AttackingBand.java.

In standard play, each band contains exactly one creature. The banding keyword (from Alpha/early sets) allows multiple creatures to form a single band. We store the full band structure for parity, but isValidBand only handles single-creature bands and explicit banding — “bands with” is stubbed.

Fields

attackers: Vec<CardId>

blocked: Option<bool>

None = not yet determined, Some(true) = blocked, Some(false) = unblocked.

Implementations

impl AttackingBand

pub fn new(card: CardId) -> Self

pub fn from_list(cards: Vec<CardId>) -> Self

pub fn get_attackers(&self) -> &[CardId]

pub fn add_attacker(&mut self, card: CardId)

pub fn remove_attacker(&mut self, card: CardId)

pub fn contains(&self, card: CardId) -> bool

Check if card is part of this band.

pub fn is_blocked(&self) -> Option<bool>

pub fn set_blocked(&mut self, value: bool)

pub fn is_empty(&self) -> bool

pub fn is_valid_band( band: &[CardId], cards: &[Card], share_damage: bool, ) -> bool

Validate that a band is legal. For starting a band (share_damage = false), all but one creature must have Banding. For sharing damage (share_damage = true), at least one must have Banding.

Full “bands with” keyword support is stubbed — returns true for single-creature bands, which covers 99.9% of actual play.

pub fn can_join_band(&self, card: CardId, cards: &[Card]) -> bool

Check if card can join this existing band.
