# Typed results

Use `brix/result` for expected failures callers can handle. Choose the synchronous `Result` workflow or Brix's awaitable `ResultPromise` workflow.

## Handle synchronous outcomes

[Model tagged errors, narrow or match branches, transform values, and chain synchronous work.](/docs/results-synchronous)

## Compose asynchronous outcomes

[Consume and adapt `ResultPromise`, use its fluent operations, and test both branches.](/docs/results-async)
