Macro roead::objs

macro_rules! objs {
    (@single $($x:tt)*) => { ... };
    (@count $($rest:expr),*) => { ... };
    ($($key:expr => $value:expr,)+) => { ... };
    ($($key:expr => $value:expr),*) => { ... };
}

Convenience macro to construct a ParameterObjectMap with map literal syntax. Example:

let plist = ParameterList {
    objects: objs!(
        "someobj" => params!(
            "someparam" => Parameter::Bool(true)
        )
    ),
    lists: Default::default()
};
