ensure()

ensure<T>(schema, input): Result<T, string>

Parses a value against a Kanon schema and returns a Zygos Result.

Bridge between Kanon validation and Zygos error handling: instead of checking result.success, you get a chainable Result<T, string>.

---

Type Parameters

T: T

The expected output type of the schema.

---

Parameters

schema: Schema<T>

Kanon schema to validate against.

input: unknown

Value to validate.

---

Returns: Result<T, string>

Ok<T> if validation succeeds, Err<string> otherwise.

import { object, string, number } from "pithos/kanon";

  .map(user => user.name.toUpperCase())
  .mapErr(error => `Validation failed: ${error}`);
