Struct v8::ObjectTemplate

#[repr(C)]
pub struct ObjectTemplate(_);

An ObjectTemplate is used to create objects at runtime.

Properties added to an ObjectTemplate are added to each object created from the ObjectTemplate.

Implementations

impl ObjectTemplate

pub fn new<'s>(scope: &mut HandleScope<'s, ()>) -> Local<'s, ObjectTemplate>

Creates an object template.

pub fn new_from_template<'s>(
    scope: &mut HandleScope<'s, ()>,
    templ: Local<'_, FunctionTemplate>
) -> Local<'s, ObjectTemplate>

Creates an object template from a function template.

pub fn new_instance<'s>(
    &self,
    scope: &mut HandleScope<'s>
) -> Option<Local<'s, Object>>

Creates a new instance of this object template.

pub fn internal_field_count(&self) -> usize

Gets the number of internal fields for objects generated from this template.

pub fn set_internal_field_count(&self, value: usize) -> bool

Sets the number of internal fields for objects generated from this template.

pub fn set_accessor(
    &self,
    key: Local<'_, Name>,
    getter: impl for<'s> MapFnTo<AccessorNameGetterCallback<'s>>
)

pub fn set_accessor_with_setter(
    &self,
    key: Local<'_, Name>,
    getter: impl for<'s> MapFnTo<AccessorNameGetterCallback<'s>>,
    setter: impl for<'s> MapFnTo<AccessorNameSetterCallback<'s>>
)

pub fn set_named_property_handler(
    &self,
    configuration: NamedPropertyHandlerConfiguration<'_>
)

pub fn set_indexed_property_handler(
    &self,
    configuration: IndexedPropertyHandlerConfiguration<'_>
)

pub fn set_accessor_property(
    &self,
    key: Local<'_, Name>,
    getter: Option<Local<'_, FunctionTemplate>>,
    setter: Option<Local<'_, FunctionTemplate>>,
    attr: PropertyAttribute
)

Sets an accessor property on the object template.

Panics

Panics if both getter and setter are None.

pub fn set_immutable_proto(&self)

Makes the ObjectTemplate for an immutable prototype exotic object, with an immutable proto.

Methods from Deref<Target = Template>

pub fn set(&self, key: Local<'_, Name>, value: Local<'_, Data>)

pub fn set_with_attr(
    &self,
    key: Local<'_, Name>,
    value: Local<'_, Data>,
    attr: PropertyAttribute
)

Adds a property to each instance created by this template with the specified property attributes.

Trait Implementations

impl Debug for ObjectTemplate

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

Formats the value using the given formatter.

impl Deref for ObjectTemplate

type Target = Template

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'s> PartialEq<Data> for ObjectTemplate

fn eq(&self, other: &Data) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'s> PartialEq<ObjectTemplate> for Data

fn eq(&self, other: &ObjectTemplate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'s> PartialEq<ObjectTemplate> for ObjectTemplate

fn eq(&self, other: &ObjectTemplate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'s> PartialEq<ObjectTemplate> for Template

fn eq(&self, other: &ObjectTemplate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'s> PartialEq<Template> for ObjectTemplate

fn eq(&self, other: &Template) -> bool
