Implementations

impl Value

pub fn type_name(&self) -> &str

Returns the name of this value’s type.

pub fn is_falsy(&self) -> bool

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<()> for Value

The unit type translates to Value::Nil.

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<Gc<String>> for Value

fn from(s: Gc<String>) -> Self

Converts to this type from the input type.

impl<T> From<Object<T>> for Valuewhere
    T: Any,

fn from(o: Object<T>) -> Self

Converts to this type from the input type.

impl<T> From<Option<T>> for Valuewhere
    T: Into<Value>,

fn from(opt: Option<T>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self
