Modules

ability

Ability – helper functions for in-play abilities. Mirrors Java’s Ability.java (base class for abilities on permanents). In Rust the subclass is flattened into SpellAbility.

ability_activated

AbilityActivated – helper functions for activated abilities. Mirrors Java’s AbilityActivated.java. In Rust the subclass is flattened: SpellAbility.is_activated == true.

ability_mana_part

Mana-producing part of an ability.

ability_static

AbilityStatic – helper functions for static abilities (e.g. morph face-up). Mirrors Java’s AbilityStatic.java. Static abilities are special actions that don’t use the stack (like turning a morph face-up).

ability_sub

AbilitySub – helper functions for sub-abilities in the chain. Mirrors Java’s AbilitySub.java. Sub-abilities are chained via SpellAbility.sub_ability and resolve sequentially after their parent.

alternative_cost

Alternative casting costs for spells and abilities.

land_ability

LandAbility – helper functions for land play abilities. Mirrors Java’s LandAbility.java. Playing a land is a special action, not a spell – it doesn’t use the stack.

optional_cost

Optional additional costs for spells.

optional_cost_value

OptionalCostValue — pairs an optional cost type with a description.

params

Typed accessor helpers for SpellAbility parameters.

runtime_types

spell

Spell – helper functions for cast spells. Mirrors Java’s Spell.java (subclass of SpellAbility for spells cast from hand/zone). In Rust the subclass is flattened: SpellAbility.is_spell == true marks a spell.

spell_ability_condition

Condition checks for spell abilities.

spell_ability_predicates

Predicate functions for filtering spell abilities.

spell_ability_restriction

Activation restrictions for spell abilities.

spell_ability_stack_instance

SpellAbilityStackInstance – stack entry for spells/abilities. Mirrors Java’s SpellAbilityStackInstance.java. The core struct is StackEntry in crate::zone::magic_stack. This module re-exports it and provides additional query methods that mirror the Java API.

spell_ability_variables

Activation/condition variables for spell abilities.

spell_permanent

SpellPermanent – factory for permanent spells. Mirrors Java’s SpellPermanent.java. Creates SpellAbility instances configured as permanent spells (creatures and non-creatures) that resolve by moving to the battlefield.

target_choices

Target choices for spell abilities.

target_restrictions

Target restrictions for spell abilities.

trait_spell_ability

ISpellAbility trait – marker trait for spell abilities. Mirrors Java’s ISpellAbility.java.

valid_sa

Structs

SpellAbility

A spell or ability with its own targeting, costs, and sub-ability chain. Mirrors Java’s SpellAbility class — each node in the chain has its own target_restrictions, target_chosen, sub_ability, api, etc.

Traits

TriggerKeyInput

Functions

choose_targets_by_kind

has_split_second_on_stack

Check whether any spell on the stack has split second. Split second prevents players from casting spells or activating abilities (except mana abilities) while it’s on the stack. Single source of truth — used by spell, ability, and ability_activated modules.
