Struct SignedExpr 

pub struct SignedExpr {
    pub id: ExprId,
    pub neg: bool,
}

A nonlinear residual summand: the existing arena node id, taken with a leading negation when neg is set. Carrying the sign as a flag. Lets split_linear run without a mutable arena.

Fields

id: ExprId

neg: bool

Trait Implementations

impl Clone for SignedExpr

fn clone(&self) -> SignedExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SignedExpr

impl Debug for SignedExpr

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

Formats the value using the given formatter.

impl Eq for SignedExpr

impl PartialEq for SignedExpr

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