Implementations

impl Expr

pub fn unary_op(self, op: UnaryOperator) -> Self

pub fn binary_op(self, rhs: Self, op: BinaryOperator) -> Self

pub fn ternary_op(self, mhs: Self, rhs: Self, op: TernaryOperator) -> Self

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl PartialEq for Expr

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