type Evaluator ¶

type Evaluator struct{}

Evaluator is a small, dependency-free visibility evaluator.

Supported operators: - boolean checks: `enabled` - comparisons: `field == true`, `field != "value"`, `count == 3` - boolean composition: `a == true && b != false`, `a || b`

Values are read from visibility.Context.Values (with dot-path traversal) and visibility.Context.Extras (via the `extras.` prefix).
