Struct JsObject

pub struct JsObject(/* private fields */);

The type of JavaScript objects, i.e., the root of all object types.

Example

// Create an object:
let obj = cx.empty_object()
    .prop(&mut cx, "name")
    .set("Neon")?
    .prop("url")
    .set("https://neon-bindings.com")?
    .this();

// Call console.log(obj):
cx.global::<JsObject>("console")?.method(&mut cx, "log")?.arg(obj)?.exec()?;

Implementations

impl JsObject

pub fn new<'a, C: Context<'a>>(c: &mut C) -> Handle<'a, JsObject>

Creates a new empty object.

Trait Implementations

impl Debug for JsObject

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

Formats the value using the given formatter.

impl Object for JsObject

fn prop<'a, 'cx: 'a, K: PropertyKey>( &self, cx: &'a mut Cx<'cx>, key: K, ) -> PropOptions<'a, 'cx, Self, K>

Create a PropOptions for accessing a property.

fn method<'a, 'cx: 'a, K: PropertyKey>( &self, cx: &'a mut Cx<'cx>, key: K, ) -> NeonResult<BindOptions<'a, 'cx>>

Gets a property from the object as a method and binds this to the object.

fn get_opt<'a, V: Value, C: Context<'a>, K: PropertyKey>( &self, cx: &mut C, key: K, ) -> NeonResult<Option<Handle<'a, V>>>
