Struct AttackRequirement 

pub struct AttackRequirement {
    pub attacker: CardId,
    pub must_attack_any: bool,
    pub must_attack_defender: Option<PlayerId>,
    pub goaded_by: Option<PlayerId>,
    pub defender_specific: HashMap<DefenderId, i32>,
}

Represents a requirement for a creature to attack. Mirrors Java’s AttackRequirement.java.

Fields

attacker: CardId

The creature that must attack.

must_attack_any: bool

True if the creature must attack any legal defender.

must_attack_defender: Option<PlayerId>

If set, the creature must attack this specific defender (if able).

goaded_by: Option<PlayerId>

The player that goaded this creature (it can’t attack that player).

defender_specific: HashMap<DefenderId, i32>

Per-defender requirement counts: defender → number of reasons to attack it. Mirrors Java’s defenderSpecific map.

Implementations

impl AttackRequirement

pub fn has_requirement(&self) -> bool

Mirrors Java’s hasRequirement(). Returns true if this creature has any reason it must attack.

pub fn count_violations(&self, defender: Option<DefenderId>) -> i32

Mirrors Java’s countViolations(). Count how many attack requirements are violated if this creature is attacking defender (or None if not attacking at all).

pub fn get_sorted_requirements(&self) -> Vec<(DefenderId, i32)>

Get sorted requirements: (defender, count) pairs sorted ascending. Mirrors Java’s getSortedRequirements().

fn clone(&self) -> AttackRequirement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
