Implementations

impl<'js> Ctx<'js>

pub fn eval<V, S>(self, source: S) -> Result<V, Error> where
    V: FromJs<'js>,
    S: Into<Vec<u8, Global>>, 

Evaluate a script in global context

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

Evaluate a script directly from a file.

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

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>), Error>

Creates promise and resolving functions.

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

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>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.
