17/// Builds and returns the `minijinja` lua table.
18///
19/// The returned table has the following keys:
20///
21/// - [`Environment`](LuaEnvironment): `userdata` provides access to a [`minijinja::Environment`]
22/// - [`None`](mlua::Value::NULL): a nil-like `lightuserdata` that can be used without the downsides
23///   of `nil`. It maps to [`minijinja::value::ValueKind::None`]
24/// - `path_loader()`: creates a callback function which can be passed to `Environment:set_loader()`
25///   to load templates from the filesystem.
26/// - `type()`: a function to return types for minijinja-lua objects.
