Trait Implementations

impl<'js> AsRef<Value<'js>> for Symbol<'js>

fn as_ref(&self) -> &Value<'js>

Converts this type into a shared reference of the (usually inferred) input type.

impl<'js> Clone for Symbol<'js>

fn clone(&self) -> Symbol<'js>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'js> Debug for Symbol<'js>

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

Formats the value using the given formatter.

impl<'js> Deref for Symbol<'js>

type Target = Value<'js>

The resulting type after dereferencing.

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

Dereferences the value.

impl<'js> From<Symbol<'js>> for Value<'js>

fn from(value: Symbol<'js>) -> Self

Converts to this type from the input type.

impl<'js> FromJs<'js> for Symbol<'js>

fn from_js(_: Ctx<'js>, value: Value<'js>) -> Result<Self>

impl<'js> IntoAtom<'js> for Symbol<'js>

fn into_atom(self, ctx: Ctx<'js>) -> Atom<'js>

impl<'js> IntoJs<'js> for Symbol<'js>

fn into_js(self, _: Ctx<'js>) -> Result<Value<'js>>

impl<'js, 't> Outlive<'t> for Symbol<'js>

type Target = Symbol<'t>

The target which has the same type as a Self but with another lifetime 't

impl<'js> PartialEq<Symbol<'js>> for Symbol<'js>

fn eq(&self, other: &Symbol<'js>) -> 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.
