Calculating Datastructures

open access: yes, 2022
AbstractWhere do datastructures come from? This paper explores how to systematically derive implementations ofone-sided flexible arraysfrom a simple reference implementation. Using the dependently typed programming language Agda, each calculation constructs an isomorphic—yet more efficient—datastructure using only a handful of laws relating types and ...
