Trait Implementations

impl Default for JSVal

fn default() -> JSVal

Returns the “default value” for a type.

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl GCMethods for Value

unsafe fn post_barrier(v: *mut Value, prev: Value, next: Value)

Place a post-write barrier

unsafe fn initial() -> Self

Create a default value

impl Initialize for Value

unsafe fn initial() -> Option<Value>

Create a default value. If there is no meaningful default possible, returns None. SAFETY: The default must not be a value that can be meaningfully garbage collected.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 RootKind for Value

const VTABLE: Self::Vtable = ()

const KIND: RootKind = JS::RootKind::Value

type Vtable = ()

impl Traceable for Value

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

Trace self.

impl Copy for Value

impl StructuralPartialEq for Value
