Struct TokenBudget 

pub struct TokenBudget {
    pub max_tokens: usize,
    pub compact_at_tokens: usize,
}

Token budget that triggers automatic compaction before the hard limit is hit.

The runtime estimates request size locally (via ModelProvider::estimate_tokens) and compacts when usage exceeds compact_at_tokens. If a request still exceeds max_tokens after compaction, the turn ends to avoid an API rejection.

compact_at_tokens defaults to 80% of max_tokens.

Fields

max_tokens: usize

Hard ceiling — the turn ends before the model is called if exceeded.

compact_at_tokens: usize

Soft ceiling — proactively compact when crossed.

Implementations

impl TokenBudget

pub fn new(max_tokens: usize) -> Self

Build a budget with compact_at_tokens set to 80% of max_tokens.

Trait Implementations

impl Clone for TokenBudget

fn clone(&self) -> TokenBudget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TokenBudget

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

Formats the value using the given formatter.

impl PartialEq for TokenBudget

fn eq(&self, other: &TokenBudget) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
