Trait Implementations

impl<'input> Clone for Expr<'input>

fn clone(&self) -> Expr<'input>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for Expr<'input>

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

Formats the value using the given formatter.

impl<'input> PartialEq for Expr<'input>

fn eq(&self, other: &Expr<'input>) -> 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.
