Implementations

source

impl Uninitialized

source

pub fn into_value<'js>(self, ctx: Ctx<'js>) -> Value<'js>

Convert into value

source

pub fn from_value<'js>(value: Value<'js>) -> Result<Self>

Convert from value

Trait Implementations

source

impl Clone for Uninitialized

source

fn clone(&self) -> Uninitialized

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for Uninitialized

source

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

Formats the value using the given formatter. Read more

source

fn eq(&self, other: &Uninitialized) -> bool

This method tests for self and other values to be equal, and is used by ==. Read more

1.0.0 · source

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. Read more
