Metadata Queries

Metadata queries return copied reflection values. They describe the registered schema and script declarations without exposing mutable runtime internals.

Types And Values

Use reflect::type_info(name) to look up a type by name and reflect::type_of(value) to inspect a value.

let player_type = reflect::type_info("Player");
let current_type = reflect::type_of(player);

if reflect::kind(player_type) == "host" {
    return reflect::fields(player_type);
}

Members And Variants

reflect::fields, reflect::methods, reflect::variants, and reflect::traits expose structured records. These records may include names, stable IDs, type hints, docs, attributes, source spans, effects, and required permissions when the registry has that data.

Modules And Functions

reflect::module, reflect::modules, reflect::function, reflect::functions, and reflect::exports describe the module/function surface installed in the current registry.

Standard modules such as math, time, option, result, set, and bytes are reflected when the engine installs the corresponding standard natives.

Missing Metadata

Host-provided schemas may not always have source spans. Missing source origins should be represented as absent metadata, not as fake file locations.
