Variable matchResultConst

Type Declaration

• • <T, E, U>(
        result: Result<T, E>,
        onOk: (value: T) => U,
        onErr: (error: E) => U,
    ): U

  • Terminal collapse — fold both tracks into a single value. Dual-form: 3-args data-first, 2-args curried for pipe. Returns whatever the handlers return.

    For files that also import match from ts-pattern, the collision-free alias matchResult is identical.

    • T
    • E
    • U

    Parameters

    • result: Result<T, E>
    • onOk: (value: T) => U

    Returns U

    Example

    const html = match(parsed, (cfg) => render(cfg), (e) => renderError(e));
