safeStrategy()

safeStrategy<In, Out>(strategy): Strategy<In, Result<Out, Error>>

Wraps a strategy to return a zygos Result instead of throwing. Catches any exception and wraps it in Err<Error>.

DEPRECATED

Use Result.fromThrowable from @zygos/result/result instead.

import { Result } from "@zygos/result/result";

const safeParseJson = Result.fromThrowable(
  (input: string) => JSON.parse(input),
  (e) => e instanceof Error ? e : new Error(String(e)),
);
safeParseJson('{"ok":true}'); // Ok({ ok: true })
safeParseJson("invalid");     // Err(SyntaxError(...))
