| (since C++20) |
The concept indirectly_comparable specifies the fundamental algorithm requirement for comparing values across two independent ranges.
indirectly_comparable is modeled only if all concepts it subsumes are modeled.

(C++20) | specifies that a callable type, when invoked with the result of dereferencing two indirectly_readable types, satisfies predicate (concept) |
