Implementations

impl TokenUsage

pub fn new() -> Self

pub fn add_request(&mut self, prompt: u64, completion: u64)

Add tokens from a request

pub fn estimate_tokens(text: &str) -> u64

Estimate token count from text (rough approximation: ~4 chars per token)

pub fn total_tokens(&self) -> u64

Get total tokens

pub fn session_duration(&self) -> Duration

pub fn estimate_cost(&self, model: &str) -> (f64, f64, f64)

Estimate cost based on model (rough estimates in USD) Returns (input_cost, output_cost, total_cost)

pub fn print_report(&self, model: &str)

Print cost report
