# Struct Diagnostics

> Cloneable activation-scoped diagnostic facade. It does not start a service. Clones share four concurrent-call slots and one in-flight read-buffer slot. Same-thread recursion into the same activation returns `DiagnosticError::Busy`.

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`.

```rust
pub struct Diagnostics { /* private fields */ }
```

Cloneable activation-scoped diagnostic facade. It does not start a service. Clones share four concurrent-call slots and one in-flight read-buffer slot. Same-thread recursion into the same activation returns [`DiagnosticError::Busy`](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-plugin/diagnostics/enum-diagnosticerror).

## Implementations

### `impl Diagnostics`

<pre />

#### `capabilities`

<pre />

Non-sensitive limits and the separately resolved read grant.

#### `availability`

<pre />

Live host availability; startup enablement remains host-owned.

#### `delivery_stats`

<pre />

Fixed local delivery totals shared by runtime/component clones.

#### `component_lazy`

<pre />

Admit a component and its vocabulary, skipping the factory when inert.

#### `reader`

<pre />

Obtain a reader only when the host explicitly grants whole-context access.

## Trait Implementations

### `impl Clone for Diagnostics`

<pre />

#### `clone`

<pre />

#### `clone_from`

<pre />
