pub fn eval_file<V: FromJs<'js>, P: AsRef<Path>>(self, path: P) -> Result<V>

Evaluate a script directly from a file.

pub fn compile<N, S>(self, name: N, source: S) -> Result<Module<'js>> where
    N: Into<Vec<u8>>,
    S: Into<Vec<u8>>, 

Compile a module for later use.

pub fn globals(self) -> Object<'js>

Returns the global object of this context.

pub fn promise(self) -> Result<(Object<'js>, Function<'js>, Function<'js>)>

Creates promise and resolving functions.

pub fn spawn<F, T>(&self, future: F) where
    F: Future<Output = T> + ParallelSend + 'static,
    T: ParallelSend + 'static, 

This is supported on crate feature futures only.

Spawn future using configured async runtime

impl<'js> Ctx<'js>

pub fn register(self, v: Value<'js>) -> RegisteryKey

This is supported on crate feature registery only.

Store a value in the registery so references to it can be kept outside the scope of context use.

A registered value can be retrieved from any context belonging to the same runtime.

pub fn deregister(self, k: RegisteryKey) -> Option<Value<'js>>

This is supported on crate feature registery only.

Remove a value from the registery.

pub fn get_register(self, k: RegisteryKey) -> Option<Value<'js>>

This is supported on crate feature registery only.

Get a value from the registery.

Trait Implementations

impl<'js> Clone for Ctx<'js>

fn clone(&self) -> Ctx<'js>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'js> Copy for Ctx<'js>

impl<'js> Debug for Ctx<'js>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
