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.

Since​

2.1.0

Example​

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

const schema = object({ name: string(), age: number() });

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