Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

JsInitError(String)

Error on js context creation. See quick_js::ContextError.

JsExecError(String)

Error on js execution. See quick_js::ExecutionError.

JsValueError(String)

Error on js value conversion. See quick_js::ValueError.
