Implementations

impl UsageTracker

pub fn new(budget_usd: Option<f64>) -> Self

pub fn record( &mut self, input: u64, output: u64, cache_read: u64, cache_write: u64, cost_usd: f64, ) -> BudgetStatus

Record a single LLM call. cost_usd should be pre-computed by the caller using ModelRegistry::estimate_cost.

pub fn budget_status(&self) -> BudgetStatus

pub fn format_bar(&self, model: &str, security_mode: &str) -> String

Format a compact status bar string for the TUI. Example: claude-sonnet-4-5 ↑12.3K ↓4.1K $0.053 [ask]
