Struct LlmSample 

pub struct LlmSample {
    pub tokens_in: u64,
    pub tokens_out: u64,
    pub cached_tokens: u64,
    pub reasoning_tokens: u64,
    pub cost_micros: Option<u64>,
}

One metered LLM request’s token/cost breakdown, passed to Metrics::record_llm_usage. Carries the four token dimensions plus the cost (present only when the model was priced). Grouping them in a struct keeps the call site readable and the four dims impossible to transpose positionally.

Fields

tokens_in: u64

tokens_out: u64

cached_tokens: u64

Cached prompt tokens (⊆ tokens_in).

reasoning_tokens: u64

Reasoning completion tokens (⊆ tokens_out).

cost_micros: Option<u64>

Cost in micro-dollars; None when the model is unpriced (tokens still counted).
