fn supported_ids() -> Vec<GenericLibfuncId>
Returns the list of generic libfuncs ids that can be instantiated through this type.
This is useful on hierarchical libfunc aggregates such as
CoreLibfunc.source§fn by_id(id: &GenericLibfuncId) -> Option<TNamedLibfunc>
fn by_id(id: &GenericLibfuncId) -> Option<TNamedLibfunc>
Instantiates the libfunc by id.
