Struct TrackerTokenUsage 

pub struct TrackerTokenUsage {
    pub prompt_tokens: usize,
    pub completion_tokens: usize,
    pub total_tokens: usize,
}

Token usage statistics (internal type for the counter module)

Note: language_models::TokenUsage is the usage returned by the LLM API (fields are usize); this TrackerTokenUsage is locally tracked cumulative usage, also usize fields, so the two convert without precision loss (Q6: unified base type, no more usize vs u32 naming clash). No TokenUsage alias is used here, to avoid confusion with language_models::TokenUsage.

Fields

prompt_tokens: usize

Cumulative prompt token count

completion_tokens: usize

Cumulative completion token count

total_tokens: usize

Cumulative total token count (prompt + completion)

Implementations

impl TrackerTokenUsage

pub fn new() -> Self

Creates empty usage statistics (all zero).

pub fn add(&mut self, prompt: usize, completion: usize)

Accumulates usage

pub fn reset(&mut self)

Resets usage statistics to all zero.
