Struct boa_engine::object::builtins::JsProxyBuilder

impl JsProxyBuilder

pub fn new(target: JsObject) -> Self

Create a new ProxyBuilder with every trap set to undefined.

pub fn apply(self, apply: NativeFunctionPointer) -> Self

Set the apply proxy trap to the specified native function.

More information:

MDN documentation

§Note

If the target object is not a function, then apply will be ignored when trying to call the proxy, which will throw a type error.

pub fn construct(self, construct: NativeFunctionPointer) -> Self

Set the construct proxy trap to the specified native function.

More information:

MDN documentation

§Note

If the target object is not a constructor, then construct will be ignored when trying to construct an object using the proxy, which will throw a type error.

pub fn define_property(self, define_property: NativeFunctionPointer) -> Self

Set the defineProperty proxy trap to the specified native function.

pub fn build(self, context: &mut Context) -> JsProxy

Build a JsObject of kind Proxy.

Equivalent to the Proxy ( target, handler ) constructor, but returns a JsObject in case there’s a need to manipulate the returned object inside Rust code.

pub fn build_revocable(self, context: &mut Context) -> JsRevocableProxy

Builds a JsObject of kind Proxy and a JsFunction that, when called, disables the proxy of the object.

Equivalent to the Proxy.revocable ( target, handler ) static method, but returns a JsObject for the proxy and a JsFunction for the revoker in case there’s a need to manipulate the returned objects inside Rust code.
