Functions ¶

func IsModule ¶

func IsModule(path string) bool

IsModule reports supported executable entry extensions.

Types ¶

type File ¶

type File struct {
	Path   string
	SHA256 string
}

File records the exact bytes used when preparing a module graph.

type Prepared ¶

type Prepared struct {
	// contains filtered or unexported fields
}

Prepared owns immutable compiled code and normalized rule data. It is safe to share across documents; each execution must open its own Scope.

func Prepare ¶

func Prepare(ctx context.Context, entry string) (*Prepared, error)

Prepare compiles a local module graph without installing packages or loading remote code. Initialization and export inspection have a five-second limit.

func PrepareWithReader ¶

func PrepareWithReader(ctx context.Context, entry string, readFile func(string) ([]byte, error)) (*Prepared, error)

PrepareWithReader compiles modules using the supplied reader for every captured file.

func (*Prepared) Data ¶

func (p *Prepared) Data() []byte

Data returns the normalized declarative ruleset, with stable callable handles.

func (*Prepared) Files ¶

func (p *Prepared) Files() []File

Files returns the local module and resolution metadata identities.

func (*Prepared) Functions ¶

func (p *Prepared) Functions() map[string]model.RuleFunction

Functions returns validation-only callable adapters for a prepared ruleset.

func (*Prepared) Open ¶

func (p *Prepared) Open(ctx context.Context, fetchConfig *config.FetchConfig) (*Scope, error)

Open initializes a fresh module instance and checks its exported contract against preparation. Module initialization must be deterministic.

type Scope ¶

type Scope struct {
	// contains filtered or unexported fields
}

Scope owns one module instance and serializes JavaScript calls for a document. Close cancels pending work and waits for the VM owner before releasing it.

func (*Scope) Close ¶

func (s *Scope) Close()

Close stops work owned by this scope. It is safe to call more than once.

func (*Scope) Functions ¶

func (s *Scope) Functions() map[string]model.RuleFunction

Functions returns adapters bound to this document scope.

func (*Scope) MatchFormats ¶

func (s *Scope) MatchFormats(ctx context.Context, data any, source string) (map[string]bool, error)

MatchFormats evaluates callable predicates against the original document once.

func (*Scope) SetNativeFunctions ¶

func (s *Scope) SetNativeFunctions(functions map[string]model.RuleFunction)

SetNativeFunctions binds existing engine functions before document execution.
