#[repr(C)]
pub struct ScriptEnvironmentPreparer { pub vtable_: *const ScriptEnvironmentPreparer__bindgen_vtable, }
Expand description

PrepareScriptEnvironmentAndInvoke asserts the embedder has registered a ScriptEnvironmentPreparer and then it calls the preparer’s ‘invoke’ method with the given |closure|, with the assumption that the preparer will set up any state necessary to run script in |global|, invoke |closure| with a valid JSContext*, report any exceptions thrown from the closure, and return.

PrepareScriptEnvironmentAndInvoke will report any exceptions that are thrown by the closure. Consumers who want to propagate back whether the closure succeeded should do so via members of the closure itself.
