Implementations

source

impl<'js> Ctx<'js>

source

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

Evaluate a script in global context

source

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

Evaluate a script directly from a file.

source

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.

source

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

Returns the global object of this context.

source

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

Creates promise and resolving functions.

source

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

source

impl<'js> Ctx<'js>

source

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.

source

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

This is supported on crate feature registery only.

Remove a value from the registery.

source

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

This is supported on crate feature registery only.

Get a value from the registery.
