TestSignalRule<C extends Cell> class

A specialized TestRule implementation for validating Signal objects within a cellular architecture.

This rule provides signal-specific validation logic to determine whether a signal should be processed by a cell's receptor. It extends the base test rule functionality with signal-specific validation.

Key characteristics:

  • Validates only Signal objects (throws ArgumentError for other types)
  • Integrates with cell test infrastructure
  • Supports user context for validation decisions
  • Composable with other test rules

Example:

// Create a test that only allows even numbers
final evenTest = TestObject<Cell>.fromRules(rules: [
 TestSignalRule<int>(rule: (signal) => signal.body?.isEven ?? false)
]);

// Apply test to a cell
final restrictedCell = Cell(test: evenTest);
