Readme for rec-smallarray-0.1.0.0

[back to package description]

rec-smallarray

GitHub Workflow Status Hackage

An immutable extensible record type based on SmallArrays, intended to provide fast reads on small structures.

Asymptotics

  • Index: Amorized O(1) with low constant factor
  • Update: O(n)
  • Slice: O(1)
  • Cons: O(n)

Note that this structure slows down GC when its size exceeds 128.

Contribution

This library started out as a module in cleff, an extensible effects library, and it needs to continue accommodating that. Contribution is welcome as long as it does not impede this library's performance nor increase its dependency footprint.
