# Struct Adaptive Hints Intercept

> Opt-in LLM request intercept that injects `AgentHints` into request headers from the prediction trie in `HotCache`.

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 AdaptiveHintsIntercept { /* private fields */ }
```

Opt-in LLM request intercept that injects [`AgentHints`](/reference/api/rust-library-reference/nemo-relay-adaptive/types/metadata/struct-agenthints) into request headers from the prediction trie in [`HotCache`](/reference/api/rust-library-reference/nemo-relay-adaptive/types/cache/struct-hotcache).

Constructed via [`AdaptiveHintsIntercept::new`](/reference/api/rust-library-reference/nemo-relay-adaptive/adaptive_hints_intercept/struct-adaptivehintsintercept) and converted to an [`LlmRequestInterceptFn`](/reference/api/rust-library-reference/nemo-relay/api/runtime/callbacks/type-llmrequestinterceptfn) via [`AdaptiveHintsIntercept::into_request_fn`](/reference/api/rust-library-reference/nemo-relay-adaptive/adaptive_hints_intercept/struct-adaptivehintsintercept) for registration with the NeMo Relay runtime.

## Implementations

### `impl AdaptiveHintsIntercept`

<pre />

#### `new`

<pre />

Creates a new `AdaptiveHintsIntercept`.

#### `into_request_fn`

<pre />

Converts this intercept into an [`LlmRequestInterceptFn`](/reference/api/rust-library-reference/nemo-relay/api/runtime/callbacks/type-llmrequestinterceptfn) suitable for registration with \[`register_llm_request_intercept`].

The returned closure reads the HotCache trie, builds AgentHints, injects them into the request headers and body, and returns the transformed request.
