Adding a named parameter

[dsgipe]

Suppose I created params with

let mut parameters = params! {
    "foo" =>  2,
};

how do I add one? For example:

parameters.insert(bar, 1).

thanks!

I figured it out.

if let Params::Named(ref mut map) = params (
map. insert( "bar".as_bytes().to_vec(), Value::from(1));
