Struct ScriptedLlm 

pub struct ScriptedLlm { /* private fields */ }

A deterministic LLM double with pre-scripted responses.

ScriptedLlm implements the real Llm trait and exercises the full runtime pipeline. Only the provider API call is replaced — everything else (session loop, checkpoints, parking, event mapping) runs exactly as it would with a real provider.

This is explicitly NOT a mock. It:

• Implements the full Llm trait contract
• Returns complete LlmResponse objects with proper Content and Part types
• Supports tool calls (function calls) in responses
• Advances through turns deterministically (FIFO order)
• Is thread-safe (Send + Sync via AtomicUsize)

Panics

If more turns are requested than were scripted, the LLM returns an empty response with turn_complete = true rather than panicking.

Implementations

impl ScriptedLlm

pub fn new(name: impl Into<String>, turns: Vec<ScriptedTurn>) -> Self

Create a new ScriptedLlm with the given name and pre-scripted turns.

Turns are consumed in FIFO order — each call to generate_content advances to the next turn.

pub fn turns_consumed(&self) -> usize

Returns the number of turns that have been consumed so far.

pub fn total_turns(&self) -> usize

Returns the total number of scripted turns.

Trait Implementations

impl Debug for ScriptedLlm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Llm for ScriptedLlm

fn name(&self) -> &str

Returns the model identifier (e.g., “gemini-2.5-flash”).

fn generate_content<'life0, 'async_trait>( &'life0 self, _request: LlmRequest, _stream: bool, ) -> Pin<Box<dyn Future<Output = AdkResult<LlmResponseStream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Generates content from the given request, optionally streaming.

fn schema_adapter(&self) -> &dyn SchemaAdapter

Returns the schema adapter for this provider.

fn uses_interactions_api(&self) -> bool

Returns true if this model is configured to use a server-managed environment (e.g., Gemini Interactions API) where the provider owns the tool-calling loop and filesystem.
