Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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<Value> for NativeCallResult

fn from(value: Value) -> Self

Converts to this type from the input type.

impl FromLustValue for Value

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

fn matches_lust_type(_: &Type) -> bool

fn type_description() -> &'static str

impl IntoLustValue for Value

fn into_value(self) -> Value

fn matches_lust_type(_: &Type) -> bool

fn type_description() -> &'static str

impl IntoTypedValue for Value

fn into_typed_value(self) -> TypedValue

impl PartialEq for Value

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