Struct TokenCounts 

pub struct TokenCounts {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cached_input_tokens: u64,
    pub reasoning_output_tokens: u64,
    pub total_tokens: u64,
}

A snapshot of token counts within a single turn or aggregated across a thread. Sub-field of TokenUsage.

Fields

input_tokens: u64

Input tokens consumed.

output_tokens: u64

Output tokens generated.

cached_input_tokens: u64

Input tokens served from cache.

reasoning_output_tokens: u64

Output tokens spent on chain-of-thought reasoning (model-dependent).

total_tokens: u64

Sum total — may be redundant with the other counts.
