btype: B-tree based collection types for Go
Summary
btype is a Go library delivering B-tree based collection types (Map, Set, Array, Table, Stack, Queue, Deque, Prique) with O(log n) operations, copy-on-write snapshots, and performance-oriented design. The README highlights automatic type ordering, custom comparators, tagged struct keys, and benchmarks comparing against other B-tree implementations; it provides practical usage examples and API details.
