    public @NonNull ParserRegistry<C> parserRegistry() {
        return this.parserRegistry;
    }
Returns the parser registry instance.
<p>
The parser registry contains default mappings to {@link ArgumentParser argument parsers} and
allows for the registration of custom mappings. The parser registry also contains mappings between
annotations and {@link ParserParameter}, which allows for the customization of parser settings by
using annotations.
<p>
When creating a new parser type, it is highly recommended to register it in the parser registry.
In particular, default parser types (shipped with cloud implementations) should be registered in the
constructor of the platform {@link CommandManager}.
