Example of Entity Component System in Go
Good question, I think there's many different lessons. To your point about bitmasks, you can imagine that each component (i.e. column) has an array of data and a large bitmap that identifies whether a component is present or not. Had to build a SIMD implementation so you can do and, and not, or and xor operations on millions of components within reasonable amount of time. Interestingly enough, you still need a hashmap or b+tree in case you want to retrieve a component by it's ID instead of an index, but the rest of things can be modeled with bitmap indexes.

willf/bloom VS bloom_cpp - a user suggested alternative

There are 87 bloom filter crates. Strategies for choosing one?
I also have a lot of sympathy for the casual user that has a bloom-filter-shaped hole in their program that all of these filters will fill, and having reduced this part of their task to a well-known solved problem, just want to plug in a random thing & move on, with the possibility of revisiting the selection later if bloomfiltering shows up in the profiler.
What are some alternatives?
When comparing bitmap and willf/bloom you can also consider the following projects:
fsm - Finite State Machine for Go
levenshtein - Go implementation to calculate Levenshtein Distance.
go-adaptive-radix-tree - Adaptive Radix Trees implemented in Go
bitset - Go package implementing bitsets
bit - Bitset data structure
null - Nullable Go types that can be marshalled/unmarshalled to/from JSON.
bloom - Bloom filters implemented in Go.
trie - Data structure and relevant algorithms for extremely fast prefix/fuzzy string searching.
hilbert - Go package for mapping values to and from space-filling curves, such as Hilbert and Peano curves.
hyperloglog - HyperLogLog with lots of sugar (Sparse, LogLog-Beta bias correction and TailCut space reduction) brought to you by Axiom
