Struct NumberUnaryOp 

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

A literal-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, NumberLiteral) -> Result<Value>

Applies the operator to a single domain literal.
