Fields

js_error_create_fn: Option<Rc<JsErrorCreateFn>>
Expand description

Allows a callback to be set whenever a V8 exception is made. This allows the caller to wrap the JsError into an error. By default this callback is set to JsError::create().

get_error_class_fn: Option<GetErrorClassFn>
Expand description

Allows to map error type to a string “class” used to represent error in JavaScript.

module_loader: Option<Rc<dyn ModuleLoader>>
Expand description

Implementation of ModuleLoader which will be called when V8 requests to load ES modules.

If not provided runtime will error if code being executed tries to load modules.

extensions: Vec<Extension>
Expand description

JsRuntime extensions, not to be confused with ES modules these are sets of ops and other JS code to be initialized.

startup_snapshot: Option<Snapshot>
Expand description

V8 snapshot that should be loaded on startup.

Currently can’t be used with will_snapshot.

will_snapshot: bool
Expand description

Prepare runtime to take snapshot of loaded code.

Currently can’t be used with startup_snapshot.

create_params: Option<CreateParams>
Expand description

Isolate creation parameters.

v8_platform: Option<UniquePtr<Platform>>
Expand description

V8 platform instance to use. Used when Deno initializes V8 (which it only does once), otherwise it’s silenty dropped.
