◆ AbslStringify

template<typename Sink >
void AbslStringify ( Sink & sink,
const IR::Node * n )
friend

Helper to simplify usage of nodes in Abseil functions (e.g. StrCat / StrFormat, etc.) without explicit string_view conversion. Note that this calls Node::toString() so might not be always appropriate for user-visible messages / strings.
