Struct FingererTreeContrib 

pub struct FingererTreeContrib {
    pub flat_fps: f64,
    pub add_percent: f64,
    pub mul_factor: Mag,
    pub cost_mul: Mag,
}

Per-fingerer contribution from the tree. Mirrors FingererAggregate (additive percent sums, mul factor multiplies, flat sums) so the FPS formula combines tree + modifier contributions symmetrically.

Multiplicative fields live in Mag (log-magnitude) because they compound across hundreds-to-thousands of bought nodes; the original f64 storage produced Infinity in long-haul play. Additive fields (flat_fps, add_percent) stay f64 — they don’t compound and per-node values stay tiny.

Fields

flat_fps: f64

add_percent: f64

mul_factor: Mag

cost_mul: Mag

Multiplicative on the buy cost of this fingerer (< 1.0 discount, > 1.0 inflation). Used by GameState::cost.

Trait Implementations

impl Clone for FingererTreeContrib

fn clone(&self) -> FingererTreeContrib

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FingererTreeContrib

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FingererTreeContrib

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FingererTreeContrib

fn eq(&self, other: &FingererTreeContrib) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
