v0.3.0 2026-09-18 Belfast

This release removed the dependency on repr (which pulled in at least 6 additional dependencies). This is a breaking change to the interfaces for constructing rtrees. However, seeing as we are <1.0.0 it is being released as a minor bump.

Existing rtree instantiations can easily fulfil the module interface using their repr runtime type representation like so:

module Line = struct
  type t = { p0 : float * float; p1 : float * float }

  let t =
    let open Repr in
    record "line" (fun p0 p1 -> { p0; p1 })
    |+ field "p0" (pair float float) (fun t -> t.p0)
    |+ field "p1" (pair float float) (fun t -> t.p1)
    |> sealr

  (* ADDED: New lines that add [equal] and [pp] functions defined
     using the existing runtime type representation. *)
  let equal = Repr.equal t |> Repr.unstage
  let pp = Repr.pp t

  type envelope = Rtree.Rectangle.t

  let envelope { p0 = (x1, y1); p1 = (x2, y2) } =
    let x0 = Float.min x1 x2 in
    let x1 = Float.max x1 x2 in
    let y0 = Float.min y1 y2 in
    let y1 = Float.max y1 y2 in
    Rtree.Rectangle.v ~x0 ~y0 ~x1 ~y1
end

module R = Rtree.Make(Rtree.Rectangle)(Line)

This is a quick fix. Users are advised to remove their dependency on repr and hand-write equal and pp functions.
