    .SYNOPSIS
        Rust PipeScript Language Definition
    .DESCRIPTION
        Defines Rust within PipeScript.

        This allows Rust to be templated.
    .EXAMPLE
        Invoke-PipeScript -ScriptBlock {
            $HelloWorldRustString = '
            fn main() {
                let msg = /*{param($msg = ''hello world'') "`"$msg`""}*/ ;
                println!("{}",msg);
            }
            '
            $HelloWorldRust = template HelloWorld_Rust.rs $HelloWorldRustString
            "$HelloWorldRust"
        }
    .EXAMPLE
        Invoke-PipeScript -ScriptBlock {
            $HelloWorldRust = template HelloWorld_Rust.rs '
            $HelloWorld = {param([Alias(''msg'')]$message = "Hello world") "`"$message`""}
            fn main() {

                println!("{}",msg);
            }
