Implementations

impl<'gc> Value<'gc>

pub fn type_name(self) -> &'static str

pub fn display<W: Write>(self, w: W) -> Result<(), Error>

pub fn is_nil(self) -> bool

pub fn to_bool(self) -> bool

Lua nil and false are false, anything else is true.

pub fn not(self) -> Value<'gc>

pub fn to_number(self) -> Option<f64>

Interprets Numbers, Integers, and Strings as a Number, if possible.

pub fn to_integer(self) -> Option<i64>

Interprets Numbers, Integers, and Strings as an Integer, if possible.

pub fn to_constant(self) -> Option<Constant<String<'gc>>>

Trait Implementations

impl<'gc> Clone for Value<'gc>

fn clone(&self) -> Value<'gc>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'gc> Collect for Value<'gc>

fn needs_trace() -> bool

As an optimization, if this type can never hold a Gc pointer and trace is unnecessary to call, you may implement this method and return false. The default implementation returns true, signaling that Collect::trace must be called.

fn trace(&self, cc: &Collection)

Must call Collect::trace on all held Gc pointers. If this type holds inner types that implement Collect, a valid implementation would simply call Collect::trace on all the held values to ensure this.

impl<'gc> Debug for Value<'gc>

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

Formats the value using the given formatter.

impl<'gc> Default for Value<'gc>

fn default() -> Self

Returns the “default value” for a type.

impl<'gc> Display for Value<'gc>

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

Formats the value using the given formatter.
