Trait Implementations

impl<T: Debug + GCMethods + Copy> Debug for Heap<T>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Trace for Heap<*mut JSFunction>

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

impl Trace for Heap<*mut JSObject>

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

impl Trace for Heap<*mut JSScript>

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

impl Trace for Heap<*mut JSString>

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

impl Trace for Heap<Value>

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

impl Trace for Heap<jsid>

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

impl<T: GCMethods + Copy> Clone for Heap<T> where
    Heap<T>: Default, 

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Default for Heap<*mut T> where
    *mut T: GCMethods + Copy, 

fn default() -> Heap<*mut T>

Returns the "default value" for a type.

impl Default for Heap<Value>

fn default() -> Heap<Value>

Returns the "default value" for a type.

impl<T: GCMethods + Copy> Drop for Heap<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: GCMethods + Copy + PartialEq> PartialEq for Heap<T>

fn eq(&self, other: &Self) -> 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 !=.

impl FromJSValConvertible for Heap<JSVal>

type Config = ()

Optional configurable behaviour switch; use () for no configuration.

unsafe fn from_jsval(
    _cx: *mut JSContext,
    value: HandleValue,
    _option: ()
) -> Result<ConversionResult<Self>, ()>

Convert val to type Self. Optional configuration of type T can be passed as the option argument. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

impl ToJSValConvertible for Heap<JSVal>

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue)

Convert self to a JSVal. JSAPI failure causes a panic.

impl ToJSValConvertible for Heap<*mut JSObject>

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue)

Convert self to a JSVal. JSAPI failure causes a panic.
