Struct runtime

pub struct runtime {}

An extension for use with the Deno JS runtime. To use it, provide it as an argument when instantiating your runtime:

use deno_core::{ JsRuntime, RuntimeOptions };

let mut extensions = vec![runtime::init_ops_and_esm()];
let mut js_runtime = JsRuntime::new(RuntimeOptions {
  extensions,
  ..Default::default()
});

Implementations

impl runtime

pub fn init_ops_and_esm() -> Extension

Initialize this extension for runtime or snapshot creation. Use this function if the runtime or snapshot is not created from a (separate) snapshot, or that snapshot does not contain this extension. Otherwise use init_ops() instead.

Returns

an Extension object that can be used during instantiation of a JsRuntime

pub fn init_ops() -> Extension

Initialize this extension for runtime or snapshot creation, excluding its JavaScript sources and evaluation. This is used when the runtime or snapshot is created from a (separate) snapshot which includes this extension in order to avoid evaluating the JavaScript twice.

Returns

an Extension object that can be used during instantiation of a JsRuntime
