```ts
type ScalarCriteria<Value = never, Raw extends string = string> = | Value
| Raw
| null
| StringFilter<Value, Raw>
```

One field's criteria: a value to equal, or a filter describing how to compare.

The bare value is shorthand for `{ equals: `[`value`](/en/ts/latest/reference/types-tmuxsubscriptionevent-value/)` }`, and [`null`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/null) matches a
field tmux reports as unset rather than empty.

## Type parameters

- `Value` (default `never`)
- `Raw` (bound `string`, default `string`)
