Struct ValueNumberUnaryOp 

pub struct ValueNumberUnaryOp {
    pub operator: Symbol,
    pub operand_domain: Symbol,
    pub cost: u16,
    pub apply: fn(&mut Cx, Value) -> Result<Value>,
}

A value-level unary operator keyed on its operand domain.

Fields

operator: Symbol

Operator symbol this rule implements.

operand_domain: Symbol

Required domain of the operand.

cost: u16

Relative cost, used to rank competing implementations.

apply: fn(&mut Cx, Value) -> Result<Value>

Applies the operator to a single domain value.

Trait Implementations

impl Clone for ValueNumberUnaryOp

fn clone(&self) -> ValueNumberUnaryOp

Returns a duplicate of the value.

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