Struct ScalarReductionOp 

pub struct ScalarReductionOp {
    pub operator: Symbol,
    pub literal_cost: u16,
    pub literal_apply: fn(&mut Cx, Vec<NumberLiteral>) -> Result<Value>,
    pub value_cost: u16,
    pub value_apply: fn(&mut Cx, Vec<Value>) -> Result<Value>,
}

One reduction op in both literal and value form.

Fields

operator: Symbol

The operator symbol this op implements (e.g. sum).

literal_cost: u16

Dispatch cost of the literal (parsed-form) implementation.

literal_apply: fn(&mut Cx, Vec<NumberLiteral>) -> Result<Value>

The literal-form implementation over a vector of number literals.

value_cost: u16

Dispatch cost of the value (opaque-object) implementation.

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

The value-form implementation over a vector of number values.
