(OP) I'm mostly interesting in a fast hash for writing a generic, concurrent hash map.

The reference to Tries came from the original issue in the Golang repo about possible uses for a standard library hash function: https://github.com/golang/go/issues/21195

And you're right, the Trie implementation linked there was indeed a Hash-Array Mapped Tried: https://pkg.go.dev/github.com/lleo/go-hamt-key#Key

related and useful: "Ribbon filter: Practically smaller than Bloom and Xor" (https://arxiv.org/abs/2103.02515)

This paper does a good job of showing the space/time tradeoffs of various approximate sets.

That sounds somewhat similar to Dolt's storage index structure: Prolly Trees https://www.dolthub.com/blog/2020-04-01-how-dolt-stores-tabl...
