Would it be possible to customize toString()?

[scarf005]

import { HashMap } from "https​://deno.land/x/rimbu​@1.0.3/hashed/mod.ts"

export type Pos = { y: number; x: number }

const map = HashMap.of<Pos, Pos>([{y:0, x:0}, {y: 0, x: 1}], [{y: 1, x:0}, {y: 1, x: 1}])

console.log(map.toString())
// HashMap([object Object] -> [object Object], [object Object] -> [object Object])

it's be nice to be able to pass in custom formatter.

I usually use map.toArray() for such purposes, or otherwise map.stream().map(entry => customToString(entry)).toArray().

But I guess it would be possible to add options to map.toString() like so: map.toString({ entryToString: (entry) => customToString(entry) }). Would that have your preference?

Alternatively, I realized that Stream also offers the join() method that can be used as follows:
map.stream().join({ valueToString: (entry) => customToString(entry), sep: ', ' })
