# Struct Diagnostic Query

> Typed diagnostic query preserving the shared runtime fields.

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 />

Typed diagnostic query preserving the shared runtime fields.

## Fields

### `schema_version: Option<u32>`

Optional required snapshot version; omission selects this runtime's version.

### `component_key: Option<String>`

Select one logical component key across retained registrations.

### `component_instance_id: Option<String>`

Select one registration incarnation.

### `origin_generation: Option<u64>`

Select recent events by original refresh generation only. Lifetime and current-refresh summaries keep their declared scope.

### `code: Option<String>`

Select exact canonical code counters and events.

### `domain: Option<i32>`

Select the authoritative catalogue parent domain.

### `plugin_family: Option<i32>`

Select the plugin catalogue family derived from code ownership.

### `failure_class: Option<String>`

Select event causes only; code counters do not retain cause breakdowns.

### `ownership: Option<DiagnosticComponentOwnership>`

Select component rows by current-refresh ownership and events by original ownership. Selected lifetime counters still span the entire component instance.

### `after_sequence: Option<u64>`

Select later recent events; summary and code counters remain cumulative.

### `max_components: Option<u32>`

Requested component-instance row cap, rejected above core limits.

### `max_events: Option<u32>`

Requested recent-event cap, rejected above core limits.

### `max_response_bytes: Option<u32>`

Requested encoded response cap, rejected above core limits.

### `continuation: Option<DiagnosticCursor>`

Resume a compatible bounded selection without granting additional scope.
