Struct InputQueue 

pub struct InputQueue(/* private fields */);

Messages waiting to join a turn already in progress. Cheap to clone; every clone shares one queue.

Implementations

impl InputQueue

pub fn new() -> Self

An empty queue.

pub fn push(&self, message: Message)

Add a message for the running turn to pick up at its next reasoning step. Never blocks and never fails: a queue with no turn draining it simply holds what it was given, and the next turn takes it.

pub fn is_empty(&self) -> bool

Whether anything is waiting. Cheaper than draining for a host that only wants to know.

pub fn drain(&self) -> Vec<Message>

Take everything queued, in the order it was pushed.

Executors call this only when the next action is a reasoning step, never mid-batch. That is a protocol constraint, not a preference: providers require every tool call to be answered by its result, so a user message wedged between a tool_use and its tool_result makes the exchange invalid. Steering therefore lands at the next model call — which is also the first moment the model could act on it anyway.
