# `BB.Error.Estimator.SyncMiss`
[🔗](https://github.com/beam-bots/bb/blob/main/lib/bb/error/estimator/sync_miss.ex#L5)

A driver input arrived but a paired non-driver input was older than
the estimator's `sync_tolerance`.

Normally the framework drops these dispatches silently (with
`[:bb, :estimator, :dropped]` telemetry, reason `:sync_miss`). This
error type exists for algorithms or supervisors that want to surface
the miss as a structured value instead.

# `t`

```elixir
@type t() :: %BB.Error.Estimator.SyncMiss{
  __exception__: true,
  bread_crumbs: term(),
  class: term(),
  driver_path: [atom()],
  gap_ms: number(),
  input_path: [atom()],
  path: term(),
  splode: term(),
  stacktrace: term(),
  tolerance_ms: number(),
  vars: term()
}
```

# `exception`

```elixir
@spec exception(opts :: Keyword.t()) :: %BB.Error.Estimator.SyncMiss{
  __exception__: true,
  bread_crumbs: term(),
  class: term(),
  driver_path: term(),
  gap_ms: term(),
  input_path: term(),
  path: term(),
  splode: term(),
  stacktrace: term(),
  tolerance_ms: term(),
  vars: term()
}
```

Create an `Elixir.BB.Error.Estimator.SyncMiss` without raising it.

## Keys

- :driver_path
- :input_path
- :gap_ms
- :tolerance_ms
