Struct PendingContext 

pub struct PendingContext { /* private fields */ }

Thread-safe buffer for pending context turns awaiting delivery.

Context is queued by the control plane (lifecycle steps 7d/7e/7f/12/13) and drained by DeferredWriter before the next user interaction.

Thread safety

Uses parking_lot::Mutex — fast uncontested locking, no poisoning. The control lane pushes once per turn; user sends drain once per frame. Contention is near-zero.

Implementations

impl PendingContext

pub fn new() -> PendingContext

Create an empty pending context buffer.

pub fn push(&self, content: Content)

Push a single context turn into the buffer.

pub fn extend(&self, contents: Vec<Content>)

Push multiple context turns into the buffer.

pub fn set_prompt(&self)

Mark that a prompt (turnComplete:true) should follow the next flush.

pub fn drain(&self) -> (Vec<Content>, bool)

Drain all pending context, returning the contents and whether to prompt.

After this call, the buffer is empty and the prompt flag is cleared.

pub fn drain_context(&self) -> Vec<Content>

Drain only context turns, leaving any pending prompt armed.

pub fn take_prompt(&self) -> bool

Take and clear the pending prompt flag without touching queued context.

pub fn clear_prompt(&self)

Clear any armed prompt without touching queued context.

pub fn has_prompt(&self) -> bool

Return whether a prompt is currently armed.

pub fn is_empty(&self) -> bool

Check if the buffer is empty (no pending context or prompt).

Trait Implementations

impl Default for PendingContext

fn default() -> PendingContext

Returns the “default value” for a type.
