Struct CallbackObject

pub struct CallbackObject<D>
where
    D: DomTypes,
{
    callback: Heap<*mut JSObject>,
    permanent_js_root: Heap<Value>,
    incumbent: Option<Dom<<D as DomTypes>::GlobalScope>>,
}

A common base class for representing IDL callback function and callback interface types.

Fields

callback: Heap<*mut JSObject>

permanent_js_root: Heap<Value>

incumbent: Option<Dom<<D as DomTypes>::GlobalScope>>

Implementations

impl<D> CallbackObject<D>

where D: DomTypes,

pub fn get(&self) -> *mut JSObject

Trait Implementations

impl<D> Drop for CallbackObject<D>

where D: DomTypes,

fn drop(&mut self)

Executes the destructor for this type.

impl<D> PartialEq for CallbackObject<D>

where D: DomTypes,

fn eq(&self, other: &CallbackObject<D>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<D> Traceable for CallbackObject<D>

where D: DomTypes + Traceable,

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
