    pub right: Box<Expr>,
}

Binary expression

Fields

left: Box<Expr>

Left-hand side of the expression

op: Operator

Implementations

impl BinaryExpr

pub fn new(left: Box<Expr>, op: Operator, right: Box<Expr>) -> Self

Create a new binary expression

Trait Implementations

impl Clone for BinaryExpr

fn clone(&self) -> BinaryExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for BinaryExpr

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

Formats the value using the given formatter.

impl Hash for BinaryExpr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<BinaryExpr> for BinaryExpr

fn eq(&self, other: &BinaryExpr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
