func Coerce ¶

func Coerce[T any](config any, defaults T) T

Coerce converts a dynamic rule config value to a typed config with defaults. Supported inputs:

• T
• *T
• map[string]any (decoded via Resolve)

Any unsupported value falls back to defaults.

func Resolve ¶

func Resolve[T any](opts map[string]any, defaults T) T

Resolve merges user options over defaults and unmarshals to typed config. If opts is nil or empty, returns defaults unchanged. This eliminates duplicated map-to-struct conversion in each rule.

Note: For slice/map fields, only nil values are replaced with defaults. An explicitly empty slice ([]string{}) preserves the empty value, allowing users to explicitly clear defaults.

func ValidateWithSchema ¶

func ValidateWithSchema(config any, schema map[string]any) error

ValidateWithSchema validates config against a JSON Schema. The schema parameter is the map[string]any returned by ConfigurableRule.Schema(). Returns nil if valid, or an error describing validation failures.
