Implementations

impl Script

pub fn realm(&self) -> &Realm

Gets the realm of this script.

pub fn parse<R: Read>( src: Source<'_, R>, realm: Option<Realm>, context: &mut Context<'_> ) -> JsResult<Self>

Abstract operation ParseScript ( sourceText, realm, hostDefined ).

Parses the provided src as an ECMAScript script, returning an error if parsing fails.

pub fn codeblock(&self, context: &mut Context<'_>) -> JsResult<Gc<CodeBlock>>

Compiles the codeblock of this script.

This is a no-op if this has been called previously.

pub fn evaluate(&self, context: &mut Context<'_>) -> JsResult<JsValue>

Evaluates this script and returns its result.

Note that this won’t run any scheduled promise jobs; you need to call Context::run_jobs on the context or JobQueue::run_jobs on the provided queue to run them.
