fromJSONfunction

A position from JSON that toJSON wrote. Nothing in it is trusted: the seed and the draws must be whole numbers in range, the algorithm (when named) must be mulberry32, and the state (when given) must be the one that seed and those draws come to. Null when the text is not JSON, is not a position, does not add up, or is of a later format than this version reads.

import { fromJSON } from "@johnmorrisdotca/tane";

function fromJSON(text: string): StreamPosition | null

import { fromJSON, toJSON } from "@johnmorrisdotca/tane";

const position = { seed: 42, draws: 3 };
console.log(fromJSON(toJSON(position)));

{ seed: 42, draws: 3 }
