Struct rquickjs::Ctx

pub struct Ctx<'js> { /* fields omitted */ }

Context in use, passed to Context::with.

Methods

impl<'js> Ctx<'js>

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

Evaluate a script in global context

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<Sa, Sb>(self, name: Sa, source: Sb) -> Result<Module<'js>> where
    Sa: Into<Vec<u8>>,
    Sb: Into<Vec<u8>>, 

Compile a module for later use.

pub fn coerce_string(self, v: Value<'js>) -> Result<String<'js>>

Coerce a value to a string in the same way javascript would coerce values.

pub fn coerce_i32(self, v: Value<'js>) -> Result<i32>

Coerce a value to a i32 in the same way javascript would coerce values.

pub fn coerce_i64(self, v: Value<'js>) -> Result<i64>

pub fn coerce_u64(self, v: Value<'js>) -> Result<u64>

pub fn coerce_f64(self, v: Value<'js>) -> Result<f64>

pub fn coerce_bool(self, v: Value<'js>) -> Result<bool>

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

Returns the global object of this context.

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

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>>

Remove a value from the registery.

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

Get a value from the registery.

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
