# Struct Native Diagnostics ApiV1

> Frozen diagnostics callback table. Status 0 means success; other values are defined by `DiagnosticError::from_status`. Read kinds: 0 discovery, 1 snapshot, 2 memory. Read output is caller-owned; `written` is zero on any failure.

<pre />

Frozen diagnostics callback table. Status 0 means success; other values are defined by `DiagnosticError::from_status`. Read kinds: 0 discovery, 1 snapshot, 2 memory. Read output is caller-owned; `written` is zero on any failure.

## Fields

### `struct_size: usize`

Actual size of this table.

### `contract_version: u32`

Independent diagnostic transport version.

### `capabilities: unsafe extern "C" fn(*const NemoRelayNativePluginRuntime, *mut Capabilities) -> u32`

Read non-sensitive capabilities for a live activation.

### `register: unsafe extern "C" fn(*const NemoRelayNativePluginRuntime, *const Registration, *mut u64) -> u32`

Register one bounded component; output token is zero on failure.

### `record: unsafe extern "C" fn(*const NemoRelayNativePluginRuntime, u64, *const Observation, *mut Receipt) -> u32`

Record once; a failed return must not be automatically retried.

### `close: unsafe extern "C" fn(*const NemoRelayNativePluginRuntime, u64) -> u32`

Close a component without requiring a data-call permit.

### `read: unsafe extern "C" fn(*const NemoRelayNativePluginRuntime, u32, Bytes, *mut u8, usize, *mut usize) -> u32`

Copy a canonical page into a caller-owned destination.
