Struct ManaPaymentContext 

pub struct ManaPaymentContext {
    pub is_spell: bool,
    pub is_activated_ability: bool,
    pub sa_on_stack: bool,
    pub type_line: Option<CardTypeLine>,
    pub card_name: Option<String>,
    pub card_color: Option<ColorSet>,
    pub chosen_types_by_source: HashMap<CardId, String>,
}

Context about what a mana payment is for, used to check restrictions.

Fields

is_spell: bool

True if paying for a spell (not an ability).

is_activated_ability: bool

True if paying for an activated ability’s cost. Distinct from is_spell so triggered abilities and effect-driven costs (UnlessCost, cumulative upkeep, …) are neither spell nor activated.

sa_on_stack: bool

True when this is the actual payment phase for a spell already announced on the stack — i.e. cast_spell.rs has already moved the card to Stack and is now running auto-pay. Java parity: mirrors AbilityManaPart.meetsManaRestrictions line 438 — if the SA we’re paying for is currently on the stack, restricted mana sources whose RestrictValid$ Spell (or similar) clause would otherwise apply are rejected. This matches Forge’s behaviour where Leyline-Immersion- style grants are effectively unusable for the cast they were announced for, leaving only unrestricted producers in the pool. Default is false so playability prediction stays optimistic.

type_line: Option<CardTypeLine>

Card type line of the spell being cast OR the source of the activated ability being paid for (for type checks like Activated.Elemental).

card_name: Option<String>

Subtypes of the spell being cast.

card_color: Option<ColorSet>

Color of the spell being cast (for Spell.Colorless-style qualifiers).

chosen_types_by_source: HashMap<CardId, String>

Chosen creature/card types keyed by mana source card ID (e.g. Cavern of Souls).
