# Errors

> UForm for JavaScript

Every error carries a `code` from the `Status` enum, spelled as the C library names it, so a caller branches on the identity of the fault:

```javascript
import { Model, Status } from "@unum-cloud/uform";

try {
  Model.loadRam("missing.safetensors");
} catch (error) {
  if (error.code === Status.Io) console.log("no such checkpoint");
}
```

`import * as uform from 'uform';`

## Status

What went wrong, one member per `uform_status_*_k` of the C interface and spelled as its canonical name.

```typescript
enum Status
```

Every error the library or this binding throws carries one as its `code`, so a caller branches on the identity of the fault rather than on which side of the boundary saw it. A [`Deferred`](#Deferred) also reports [`Success`](#Success), and [`Deferred`](#Deferred) until its call is final.

- `Success` = `"success"`
- `Deferred` = `"deferred"`
- `OutOfMemory` = `"out-of-memory"`
- `ShapeMismatch` = `"shape-mismatch"`
- `UnsupportedLayout` = `"unsupported-layout"`
- `UnknownKind` = `"unknown-kind"`
- `Io` = `"io"`
- `Device` = `"device"`
- `Malformed` = `"malformed"`
- `Internal` = `"internal"`
- `ConfigMismatch` = `"config-mismatch"`
- `Contended` = `"contended"`
- `Cancelled` = `"cancelled"`
- `Unsupported` = `"unsupported"`
- `InvalidArgument` = `"invalid-argument"`

## UFormError

An error thrown by the library or this binding, its `code` naming the failure.

```typescript
interface UFormError extends Error
```

- `code` `Status`
