Struct ManaConversionMatrix 

pub struct ManaConversionMatrix { /* private fields */ }

Mana conversion/restriction matrix controlling what colors can pay for what.

Mirrors Java’s forge.game.mana.ManaConversionMatrix.

The conversion matrix ORs byte values to make mana more payable (additive). The restriction matrix ANDs byte values to make mana less payable (restrictive).

Implementations

impl ManaConversionMatrix

pub fn new() -> Self

Create a new matrix with identity conversion and no restrictions. Mirrors Java’s constructor which calls restoreColorReplacements().

pub fn get_possible_color_uses(&self, color: u8) -> u8

Get the effective color uses for a given color after applying conversion and restriction. Mirrors Java’s ManaConversionMatrix.getPossibleColorUses().

pub fn adjust_color_replacement( &mut self, original: u8, replacement: u8, additive: bool, )

Adjust color replacement: additive ORs into conversion, restrictive ANDs into restriction. Mirrors Java’s ManaConversionMatrix.adjustColorReplacement().

pub fn apply_card_matrix(&mut self, other: &ManaConversionMatrix)

Merge another matrix into this one: OR conversion, AND restriction. Mirrors Java’s ManaConversionMatrix.applyCardMatrix().

pub fn restore_color_replacements(&mut self)

Reset to identity: each color pays only itself, no restrictions. Mirrors Java’s ManaConversionMatrix.restoreColorReplacements().

pub fn is_snow_for_color(&self) -> bool

Whether snow mana can substitute for colored mana. Mirrors Java’s ManaConversionMatrix.isSnowForColor().

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

Set whether snow mana can substitute for colored mana. Mirrors Java’s ManaConversionMatrix.setSnowForColor().
