Member	Description
constructor(definition)	Constructor method. Returns a value of type rell.meta describing the specified definition. The definition can be an entity, object, operation, query.
simple_name: text	Represents the simple name of the definition. For example, bar if the full name is lib:foo.bar.
full_name: text	Represents the full name, including the module name, in the format <module_name>:[<namespace_path>.]<simple_name>. For instance, :foo for the root module, my_module:bar, or my_module:my_namespace.bar.
module_name: text	Represents the module name. It can be an empty string for the root module.
mount_name: text	Represents the mount name. If the definition has a mount name, it provides the mount name; otherwise, it generates a runtime error. All supported definitions have mount names.

Example - getting the mount name of an operation

operation my_op() {}
query get_op_name() = rell.meta(my_op).mount_name;

This example retrieves the mount name of the my_op operation.
