[][src]Struct deno_core::EsIsolate

pub struct EsIsolate(_);

More specialized version of CoreIsolate that provides loading and execution of ES Modules.

Creating EsIsolate requires to pass loader argument that implements ModuleLoader trait - that way actual resolution and loading of modules can be customized by the implementor.

Implementations

impl EsIsolate[src]

pub fn new(
    loader: Rc<dyn ModuleLoader>,
    startup_data: StartupData,
    will_snapshot: bool
) -> Self
[src]

pub fn mod_evaluate(&mut self, id: ModuleId) -> Result<(), ErrBox>[src]

Evaluates an already instantiated ES module.

ErrBox can be downcast to a type that exposes additional information about the V8 exception. By default this type is JSError, however it may be a different type if CoreIsolate::set_js_error_create_fn() has been used.

pub async fn load_module<'_, '_>(
    &'_ mut self,
    specifier: &'_ ModuleSpecifier,
    code: Option<String>
) -> Result<ModuleId, ErrBox>
[src]

Asynchronously load specified module and all of it's dependencies

User must call Isolate::mod_evaluate with returned ModuleId manually after load is finished.

pub fn snapshot(&mut self) -> StartupData[src]

pub fn state(isolate: &Isolate) -> Rc<RefCell<EsIsolateState>>[src]

Methods from Deref<Target = CoreIsolate>

pub fn execute(
    &mut self,
    js_filename: &str,
    js_source: &str
) -> Result<(), ErrBox>
[src]

Executes traditional JavaScript code (traditional = not ES modules)

ErrBox can be downcast to a type that exposes additional information about the V8 exception. By default this type is JSError, however it may be a different type if CoreIsolate::set_js_error_create_fn() has been used.

pub fn snapshot(&mut self) -> StartupData[src]

Takes a snapshot. The isolate should have been created with will_snapshot set to true.

ErrBox can be downcast to a type that exposes additional information about the V8 exception. By default this type is JSError, however it may be a different type if CoreIsolate::set_js_error_create_fn() has been used.

pub fn register_op<F>(&mut self, name: &str, op: F) -> OpId where
    F: Fn(&mut CoreIsolateState, &[u8], &mut [ZeroCopyBuf]) -> Op + 'static, 
[src]

Defines the how Deno.core.dispatch() acts. Called whenever Deno.core.dispatch() is called in JavaScript. zero_copy_buf corresponds to the second argument of Deno.core.dispatch().

Requires runtime to explicitly ask for op ids before using any of the ops.
