Function Documentation

constexpr auto ripple::math::hash_combine(uint32_t a, uint32_t b) noexcept -> uint64_t

Constexpr hash of two 32 bit unsigned ints.

This uses the cantour pairing formula and is composible, i.e it can be used twice for 3 ints, etc.

Note

: It is possible that this overflows for large values of a and b, so test for different use cases.

Return

The combined hash of the two inputs.

Parameters

• a: The first int for the hash.

• b: The second input for the hash.
