    ( $vec:expr, $($x:ident),* ) => { ... };
}
Expand description

Given a Value of type ValueType::VectorType it declares variables with the provided names.

The generated code may return and Err(ErrorType) and should be executed in a function that expects an EvalResult<...> as result.

ยงExamples

use num_parser::{*, function:: *};

fn read_values() -> EvalResult<()> {
     
    let vec_values = Value::Vector(vec![
        Value::from(1),
        Value::from(7),
        Value::from(-9)
    ]);
     
    read_vec_values!(vec_values, foo, bar, baz);
     
    assert_eq!(foo, &Value::from(1));
    assert_eq!(bar, &Value::from(7));
    assert_eq!(baz, &Value::from(-9));
    Ok(())
}
