```haskell
data Outcome
```

First caller result. Later evidence can retire responsibility without
 rewriting [`OutcomeUnknown`](/en/haskell/latest/reference/libtmux-server-v-outcomeunknown/) or [`ConnectionRetired`](/en/haskell/latest/reference/libtmux-server-v-connectionretired/).

## Members

### Common operations

- [`Failed`](/en/haskell/latest/reference/libtmux-server-v-failed/) (data constructor): Validated command failure.
- [`OutcomeUnknown`](/en/haskell/latest/reference/libtmux-server-v-outcomeunknown/) (data constructor): Dispatch may have happened; completion remains uncertain.

### Other members

- [`ConnectionRetired`](/en/haskell/latest/reference/libtmux-server-v-connectionretired/) (data constructor): The connection retired while responsibility remained.
- [`NotDispatched`](/en/haskell/latest/reference/libtmux-server-v-notdispatched/) (data constructor): Proof that the operation was never dispatched.
- [`Succeeded`](/en/haskell/latest/reference/libtmux-server-v-succeeded/) (data constructor): Validated successful response and completion proof.
