Struct IsExpr 

pub struct IsExpr {
    pub target: String,
    pub expr: ArithExpr,
}

Is-expression for variable binding: Z is X + Y

Fields

target: String

Target variable (must be a fresh, unbound variable).

expr: ArithExpr

Arithmetic expression to evaluate.

Trait Implementations

impl Clone for IsExpr

fn clone(&self) -> IsExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IsExpr

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

Formats the value using the given formatter.

impl PartialEq for IsExpr

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