Flat Collections

A library that provides lightweight and memory-efficient associative data structures.

Asymptotics:

operation average worst best
lookup O(logn) O(logn) O(logn)
insert O(n) O(n) O(1)
remove O(n) O(n) O(1)

Insert and remove work in O(1) when dealing with last element.

Types:

  • FlatMap - mutable map, backed by Vec
  • FlatSet - mutable set, backed by FlatMap

No runtime deps
