Struct JavaScriptValidator 

pub struct JavaScriptValidator { /* private fields */ }

JavaScript constraint validator

Executes JavaScript code for constraint validation using a sandboxed runtime. The JavaScript code should define a function validate(value, parameters) that returns a boolean or an object with valid: boolean and optional message: string.

Implementations

impl JavaScriptValidator

pub fn new( component_id: ConstraintComponentId, metadata: ComponentMetadata, code: String, ) -> Self

Create a new JavaScript validator

pub fn with_config(self, config: RuntimeConfig) -> Self

Create with custom configuration

pub fn with_security_policy(self, policy: SecurityPolicy) -> Self

Create with custom security policy

pub fn execute( &self, _value: &Term, _parameters: &HashMap<String, Term>, ) -> Result<ComponentExecutionResult>

Execute JavaScript validation.

No sandboxed JavaScript runtime is wired into this build, so a configured JavaScript validator MUST NOT silently report conformance (which would pass every focus node regardless of the actual validation logic). Instead this fails loud with ShaclError::UnsupportedOperation, in line with the project’s fail-loud contract. Wiring a real sandboxed engine (e.g. QuickJS via rquickjs, or Boa) would replace this method body.

pub fn validate_code(&self) -> Result<()>

Validate the JavaScript code syntax

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CustomConstraintComponent for JavaScriptValidator

fn component_id(&self) -> &ConstraintComponentId

Get the component identifier

fn metadata(&self) -> &ComponentMetadata

fn sparql_template(&self) -> Option<&str>

Get the SPARQL query template for this component (if SPARQL-based)

fn sparql_prefixes(&self) -> Option<&str>

Get additional prefixes needed for SPARQL queries

impl Debug for JavaScriptValidator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
