Trait Implementations

impl Clone for ExprValue

fn clone(&self) -> ExprValue

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Debug for ExprValue

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

Formats the value using the given formatter.

impl PartialEq for ExprValue

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