Crate ternary_spreadsheet 

Ternary Spreadsheet

Core logic for the SuperInstance Spreadsheet — a familiar spreadsheet interface where every cell is a tiny ternary intelligence.

Structs

Cell

A single ternary cell with value, fitness, and history.

FormulaEngine

The formula engine evaluates spreadsheet formulas against a grid.

Grid

A 2D grid of ternary cells.

MutationConfig

Configuration for autofill mutation.

Enums

FitnessColor

Color assigned based on fitness score.

FormulaError

Errors that can occur during formula evaluation.

SortAxis

Axis to sort by.

TernaryValue

A ternary value: negative, neutral, or positive.

Functions

autofill_mutate

Autofill a range with mutation. Takes the source cell’s value and propagates it across the target range, applying random mutations based on the config. Returns the number of cells mutated.

conditional_format

Assign a fitness color to a cell.

conditional_format_with_thresholds

Assign fitness colors with custom thresholds.

fitness_heatmap

Compute a heatmap of fitness values for the entire grid. Returns a Vec<Vec> where each value is normalized to [0.0, 1.0].

format_cells

Format a slice of cells into their color codes.

sort_by_fitness

Sort rows or columns by their total fitness (descending = fittest first).

Type Aliases

FormulaResult

Result of a formula evaluation.
