Rust AI Agent SDK

Budget constraints for extended thinking. Controls how much thinking/reasoning the LLM can do before producing a response.

Fields

Name	Type	Description
max_tokens	usize	Maximum tokens for thinking
max_time_seconds	Option<f64>	Maximum time in seconds (optional)
adaptive	bool	Whether to adapt budget based on complexity
level	Option<BudgetLevel>	Budget level (if using predefined)
min_tokens	usize	Minimum tokens for adaptive budgeting
complexity_multiplier	f64	Complexity multiplier for adaptive budgeting

Methods

new

fn new() -> ThinkingBudgetBuilder

Create a new ThinkingBudget with default values.

from_level

fn from_level(level: BudgetLevel) -> Self

Create a budget from a predefined level.

Parameters:

Name	Type
level	BudgetLevel

minimal

fn minimal() -> Self

Create a minimal budget.

low

fn low() -> Self

Create a low budget.

medium

fn medium() -> Self

Create a medium budget.

high

fn high() -> Self

Create a high budget.

maximum

fn maximum() -> Self

Create a maximum budget.

get_tokens_for_complexity

fn get_tokens_for_complexity(&self, complexity: f64) -> usize

Get token budget based on task complexity. # Arguments * complexity - Complexity score (0.0 to 1.0) # Returns Adjusted token budget

Parameters:

Name	Type
complexity	f64

to_map

fn to_map(&self) -> HashMap<String, serde_json::Value>

Convert to HashMap for serialization.
