Struct AdapterUsage 

pub struct AdapterUsage {
    pub input_tokens: Option<u64>,
    pub output_tokens: Option<u64>,
    pub total_tokens: Option<u64>,
    pub cached_input_tokens: Option<u64>,
    pub reasoning_tokens: Option<u64>,
    pub tool_input_tokens: Option<u64>,
}

A provider’s cumulative usage snapshot for one HTTP attempt.

Missing, invalid or negative counts remain unknown. A present zero is a reported zero. These fields may overlap (for example cached tokens are included in input tokens); never sum fields to invent a total. A later snapshot replaces the earlier snapshot, including its unknown fields.

Fields

input_tokens: Option<u64>

Input tokens, including cached input where the provider includes it.

output_tokens: Option<u64>

Output candidate tokens, as reported by the provider.

total_tokens: Option<u64>

Provider-reported total, not a sum of the other fields.

cached_input_tokens: Option<u64>

Cached input tokens, when reported.

reasoning_tokens: Option<u64>

Reasoning tokens, when reported separately.

tool_input_tokens: Option<u64>

Provider tool-use input tokens, when reported separately.
