# Enum Diagnostic Error

> Diagnostic operation error. These values never classify plugin execution.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

<pre />

Diagnostic operation error. These values never classify plugin execution.

## Variants (Non-exhaustive)

### `Unsupported`

<pre />

Host has no compatible native diagnostics extension.

### `Unavailable`

<pre />

Diagnostic adapter backing could not be admitted.

### `Closed`

<pre />

Activation or registration was closed.

### `PermissionDenied`

<pre />

Host did not grant whole-context read access.

### `Busy`

<pre />

Re-entrant call or exhausted bounded admission; no automatic retry occurs.

### `Capacity`

<pre />

Registration or request exceeds its capacity.

### `Invalid`

<pre />

Input or handle is invalid.

### `Conflict`

<pre />

A local component name is already registered.

### `BufferTooSmall`

<pre />

Caller-owned output buffer is too small.

### `Internal`

<pre />

Internal adapter failure; acceptance is not safe to retry.

### `Read(DiagnosticReadReason)`

<pre />

Canonical core read reason.

## Implementations

### `impl DiagnosticError`

<pre />

#### `reason`

<pre />

Stable bounded error label without producer-supplied text.

#### `from_status`

<pre />

Convert the frozen native status representation; unknown values fail closed.

#### `status`

<pre />

Frozen native representation; 0 and 1 are reserved for accepted/disabled.
