Struct ManaCost 

pub struct ManaCost { /* private fields */ }

A complete mana cost (e.g. {2}{W}{U}). Mirrors Java ManaCost. Immutable once constructed.

Implementations

impl ManaCost

pub fn no_cost() -> Self

Represents a card with no mana cost (e.g. lands).

pub fn zero() -> Self

Zero mana cost {0}.

pub fn generic(n: i32) -> Self

Pure generic cost (e.g. {3}).

pub fn parse(s: &str) -> Self

Parse a mana cost string in Forge format (space-separated tokens). E.g. “2 W U”, “3 G G”, “X R”, “0”, “W/U W/U”.

pub fn cmc(&self) -> i32

pub fn color_profile(&self) -> u8

pub fn color_set(&self) -> ColorSet

pub fn generic_cost(&self) -> i32

pub fn shards(&self) -> &[ManaCostShard]

pub fn is_no_cost(&self) -> bool

pub fn is_zero(&self) -> bool

pub fn is_pure_generic(&self) -> bool

pub fn count_x(&self) -> usize

pub fn has_phyrexian(&self) -> bool

pub fn from_parts(shards: Vec<ManaCostShard>, generic_cost: i32) -> ManaCost

Build a ManaCost from explicit shards and generic cost.

pub fn without_x(&self) -> ManaCost

Return a copy of this cost with all X shards removed. Used to compute the non-X portion for affordability checks.

pub fn without_phyrexian(&self) -> ManaCost

Return a copy of this cost with all Phyrexian shards removed. Used for playability checks — Phyrexian shards can always be paid with 2 life.

pub fn phyrexian_to_colored(&self) -> ManaCost

Convert phyrexian shards to their colored equivalents (e.g. {B/P} → {B}). Non-phyrexian shards are kept as-is. Generic cost is preserved.

pub fn colored_to_phyrexian(&self, color_mask: u8) -> ManaCost

Convert mono-colored shards of the given color into their phyrexian variants. Used for effects like “you may pay 2 life rather than pay {B}”.

pub fn shard_count(&self, which: ManaCostShard) -> usize

pub fn add(&self, other: &ManaCost) -> ManaCost

Add another mana cost to this one, returning the combined cost.

pub fn reduce_generic(&self, amount: i32) -> ManaCost

Reduce the generic portion of this cost by amount (floor at 0). Used for Emerge (cost reduced by sacrificed creature’s mana value).

pub fn with_generic(&self, generic: i32) -> ManaCost

Return a copy with the generic cost set to the given value.

pub fn has_color_shard(&self, atom: u16) -> bool

Check if this cost has a mono-color shard matching the given ManaAtom.

pub fn remove_color_shard(&self, atom: u16) -> ManaCost

Remove one mono-color shard matching the given ManaAtom. Returns new cost.

pub fn reduce_color( &self, color: Color, count: i32, ignore_generic: bool, ) -> ManaCost

Remove up to count colored shards matching color from this cost. If ignore_generic is true, only removes colored shards (never converts to generic reduction). If ignore_generic is false and fewer matching shards exist than count, the remainder reduces the generic portion instead.

pub fn combine(a: &ManaCost, b: &ManaCost) -> ManaCost
