Trait Implementations

impl Clone for Null

fn clone(&self) -> Null

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Null

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

Formats the value using the given formatter.

impl<'js> FromJs<'js> for Null

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

impl<'js> IntoJs<'js> for Null

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

impl PartialEq for Null

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