Struct ReportedTurnUsage 

pub struct ReportedTurnUsage {
    pub input_tokens: u64,
    pub cached_input_tokens: u64,
    pub cache_write_input_tokens: u64,
    pub output_tokens: u64,
    pub reasoning_output_tokens: u64,
    pub total_tokens: u64,
    pub estimated_cost: Option<EstimatedUsdCost>,
    pub cost_status: CostStatus,
}

Exact turn usage reported by an external backend.

Every field is named and required so wire adapters cannot silently swap or default adjacent token counters.

Fields

input_tokens: u64

All input tokens billed or reported by the backend.

cached_input_tokens: u64

Input tokens served from the backend’s prompt cache.

cache_write_input_tokens: u64

Input tokens newly written into the backend’s prompt cache.

output_tokens: u64

All output tokens billed or reported by the backend.

reasoning_output_tokens: u64

Reasoning tokens included within output_tokens.

total_tokens: u64

Backend-reported aggregate token count.

estimated_cost: Option<EstimatedUsdCost>

Exact retained cost estimate, when one was reported.

cost_status: CostStatus

Availability and provenance of estimated_cost.
