# Struct Diagnostic Event

> One retained observation, its attribution, occurrence delta, and optional evidence.

Generated from `cargo doc --no-deps -p nemo-relay-builtins -p nemo-relay-diagnostics -p nemo-relay-logging -p nemo-relay-plugin-host -p nemo-relay-codecs -p nemo-relay -p nemo-relay-runtime -p nemo-relay-model-pricing -p nemo-relay-resource-metrics -p nemo-relay-observability -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 />

One retained observation, its attribution, occurrence delta, and optional evidence.

## Fields

### `sequence: u64`

Unique source-local update sequence; it is not an occurrence counter.

### `observe_time: Option<Timestamp>`

Source observation time, preserved through projections.

### `component: Option<DiagnosticComponentIdentity>`

Registration that owned the original observation.

### `origin: Option<DiagnosticOrigin>`

Original configuration attribution, preserved through component refresh.

### `remote: Option<RemoteDiagnosticOrigin>`

Authenticated remote submission provenance, absent for local observations.

### `classification: Option<DiagnosticClassification>`

Canonical event classification; never reconstructed from a latest message.

### `context: Option<DiagnosticPluginContext>`

Bounded plugin-operation wire facts, excluded from aggregation keys.

### `severity: i32`

Evidence severity, independent of its observed operation outcome.

### `outcome: i32`

Explicit observed operation outcome.

### `detail: Option<DiagnosticDetail>`

Bounded optional evidence; absence does not imply a missing counter.

### `count: u64`

Input occurrence delta represented by this recording call.

### `correlation: Option<DiagnosticCorrelation>`

Restricted caller correlation, excluded from aggregation identity.

## Implementations

### `impl DiagnosticEvent`

#### `outcome`

<pre />

Returns the enum value of `outcome`, or the default if the field is set to an invalid enum value.
