Struct boa::object::ConstructorBuilder

pub struct ConstructorBuilder<'context> { /* private fields */ }

Builder for creating constructors objects, like Array.

Implementations

impl<'context> ConstructorBuilder<'context>

pub fn new(context: &'context mut Context, constructor: NativeFunction) -> Self

Create a new ConstructorBuilder.

pub fn method<B>(
    &mut self,
    function: NativeFunction,
    binding: B,
    length: usize
) -> &mut Selfwhere
    B: Into<FunctionBinding>,

Add new method to the constructors prototype.

pub fn static_method<B>(
    &mut self,
    function: NativeFunction,
    binding: B,
    length: usize
) -> &mut Selfwhere
    B: Into<FunctionBinding>,

Add new static method to the constructors object itself.

pub fn property<K, V>(
    &mut self,
    key: K,
    value: V,
    attribute: Attribute
) -> &mut Selfwhere
    K: Into<PropertyKey>,
    V: Into<JsValue>,

Add new data property to the constructor’s prototype.

pub fn static_property<K, V>(
    &mut self,
    key: K,
    value: V,
    attribute: Attribute
) -> &mut Selfwhere
    K: Into<PropertyKey>,
    V: Into<JsValue>,

Add new static data property to the constructor object itself.

pub fn accessor<K>(
    &mut self,
    key: K,
    get: Option<JsObject>,
    set: Option<JsObject>,
    attribute: Attribute
) -> &mut Selfwhere
    K: Into<PropertyKey>,

Add new accessor property to the constructor’s prototype.

pub fn static_accessor<K>(
    &mut self,
    key: K,
    get: Option<JsObject>,
    set: Option<JsObject>,
    attribute: Attribute
) -> &mut Selfwhere
    K: Into<PropertyKey>,

Add new static accessor property to the constructor object itself.

pub fn property_descriptor<K, P>(&mut self, key: K, property: P) -> &mut Selfwhere
    K: Into<PropertyKey>,
    P: Into<PropertyDescriptor>,

Add new property to the constructor’s prototype.

pub fn static_property_descriptor<K, P>(
    &mut self,
    key: K,
    property: P
) -> &mut Selfwhere
    K: Into<PropertyKey>,
    P: Into<PropertyDescriptor>,

Add new static property to the constructor object itself.

pub fn length(&mut self, length: usize) -> &mut Self

Specify how many arguments the constructor function takes.

Default is 0.

pub fn name<N>(&mut self, name: N) -> &mut Selfwhere
    N: AsRef<str>,

Specify the name of the constructor function.

Default is "[object]"

pub fn callable(&mut self, callable: bool) -> &mut Self

Specify whether the constructor function can be called.

Default is true

pub fn constructable(&mut self, constructable: bool) -> &mut Self

Specify whether the constructor function can be called with new keyword.

Default is true

pub fn inherit(&mut self, prototype: JsValue) -> &mut Self

Specify the prototype this constructor object inherits from.

Default is Object.prototype

pub fn context(&mut self) -> &mut Context

Return the current context.

pub fn build(&mut self) -> JsObject

Build the constructor function object.
