Trait Implementations

impl<V: JSValueImpl> Clone for JSValue<V>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V> Debug for JSValue<V>

where V: JSTypeOf + JSValueConversion,

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

Formats the value using the given formatter.

impl<V> Display for JSValue<V>

where V: JSTypeOf + JSValueConversion,

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

Formats the value using the given formatter.

impl<V: JSValueImpl> From<JSDate<V>> for JSValue<V>

fn from(date: JSDate<V>) -> Self

Converts to this type from the input type.

impl<V> From<JSValue<V>> for JSObject<V>

where V: JSValueImpl,

fn from(v: JSValue<V>) -> Self

Converts to this type from the input type.

fn into_js_value(self, _ctx: &JSContext<V::Context>) -> JSValue<V>

impl<V: JSValueImpl> PartialEq for JSValue<V>

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