Struct TokenBudgetBuilder 

pub struct TokenBudgetBuilder {
    total: i32,
    system: f32,
    instructions: f32,
    evidence: f32,
    memory: f32,
    tool_results: f32,
    history: f32,
    slack: f32,
}

Builder for constructing TokenBudget with custom ratios.

Provides a fluent API for configuring token budget allocation. All ratios default to the standard allocation if not specified.

Fields

total: i32

system: f32

instructions: f32

evidence: f32

memory: f32

tool_results: f32

history: f32

slack: f32

Implementations

impl TokenBudgetBuilder

fn new(total: i32) -> Self

Create a new builder with default ratios.

pub fn system(self, ratio: f32) -> Self

Set the system prompt ratio (default: 0.10).

pub fn instructions(self, ratio: f32) -> Self

Set the instructions ratio (default: 0.15).

pub fn evidence(self, ratio: f32) -> Self

Set the evidence ratio (default: 0.15).

pub fn memory(self, ratio: f32) -> Self

Set the memory ratio (default: 0.20).

pub fn tool_results(self, ratio: f32) -> Self

Set the tool results ratio (default: 0.15).

pub fn history(self, ratio: f32) -> Self

Set the history ratio (default: 0.20).

pub fn slack(self, ratio: f32) -> Self

Set the slack ratio (default: 0.05).

pub fn build(self) -> TokenBudget

Build the TokenBudget.

Converts ratios to absolute token counts based on total. Validates that segment ratios sum to 1.0 (±0.05 tolerance).
