Struct ContextBudget 

pub struct ContextBudget { /* private fields */ }

Assembles messages from multiple context slots within a token budget.

Slots are sorted by priority (lowest value = highest priority). Higher-priority slots are included first. Lower-priority slots are dropped if the budget is exceeded.

Implementations

impl ContextBudget

pub fn new(max_tokens: usize, counter: Arc<dyn TokenCounter>) -> Self

pub fn assemble(&self, slots: Vec<ContextSlot>) -> Vec<Message>

Assemble messages from slots that fit within the token budget.

Slots are processed in priority order (CRITICAL first, LOW last). Each slot’s messages are included if they fit. Slots with reserved_tokens > 0 are guaranteed inclusion (if total reserved fits within budget).
