Trait Implementations

impl Clone for Val

fn clone(&self) -> Val

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Val

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

Formats the value using the given formatter.

impl From<ExternRef> for Val

fn from(val: ExternRef) -> Self

Converts to this type from the input type.

impl From<FuncRef> for Val

fn from(val: FuncRef) -> Self

Converts to this type from the input type.

impl From<Ref> for Val

fn from(val: Ref) -> Self

Converts to this type from the input type.

impl From<f32> for Val

fn from(val: f32) -> Self

Converts to this type from the input type.

impl From<f64> for Val

fn from(val: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Val

fn from(val: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Val

fn from(val: i64) -> Self

impl PartialEq for Val

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

impl Copy for Val

impl StructuralPartialEq for Val
