Expand description

The trait of all object types.

Provided Methods§

Source

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

Gets a property from a JavaScript object that may be undefined and attempts to downcast the value if it existed.

Source

fn get_value<'a, C: Context<'a>, K: PropertyKey>( &self, cx: &mut C, key: K, ) -> NeonResult<Handle<'a, JsValue>>

Gets a property from a JavaScript object as a JsValue.

If a getter is defined on the object, it will be called.

Source

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

Gets a property from a JavaScript object and attempts to downcast as a specific type. Equivalent to calling obj.get_value(&mut cx)?.downcast_or_throw(&mut cx).

Throws an exception if the value is a different type.

Source

fn get_own_property_names<'a, C: Context<'a>>( &self, cx: &mut C, ) -> JsResult<'a, JsArray>

Available on crate feature napi-6 only.
Source

fn freeze<'a, C: Context<'a>>(&self, cx: &mut C) -> NeonResult<&Self>

Source

fn seal<'a, C: Context<'a>>(&self, cx: &mut C) -> NeonResult<&Self>

Source

fn set<'a, C: Context<'a>, K: PropertyKey, W: Value>( &self, cx: &mut C, key: K, val: Handle<'_, W>, ) -> NeonResult<bool>

Source

fn root<'a, C: Context<'a>>(&self, cx: &mut C) -> Root<Self>

Source

fn call_method_with<'a, C, K>( &self, cx: &mut C, method: K, ) -> NeonResult<CallOptions<'a>>
where C: Context<'a>, K: PropertyKey,

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
