Macro params 

macro_rules! params {
    () => { ... };
    ($($key:expr => $value:expr),+ $(,)?) => { ... };
}

Builds a Parameters map from a list of "name" => value pairs.

Each value is passed through Into::<Param>::into, so Rust literals ("text", 42i64, true) become Param::Literal automatically. For references, templates, arrays, and maps, use the constructors on Param directly.
