Struct TokenUsage 

pub struct TokenUsage {
    pub input_tokens: Option<u64>,
    pub output_tokens: Option<u64>,
    pub cached_input_tokens: Option<u64>,
    pub cache_creation: Vec<CacheCreation>,
    pub reasoning_tokens: Option<u64>,
}

Reported counts only. None is unknown; Some(0) is an explicit zero.

Fields

input_tokens: Option<u64>

Ordinary input, excluding cache reads and cache creation.

output_tokens: Option<u64>

Total output including reasoning; reasoning is a subset, not additive.

cached_input_tokens: Option<u64>

cache_creation: Vec<CacheCreation>

Reported writes grouped by retention. Empty means unreported.

reasoning_tokens: Option<u64>
