Struct UsageInfo 

pub struct UsageInfo {
    pub prompt_tokens: u32,
    pub completion_tokens: u32,
    pub total_tokens: u32,
    pub prompt_cache_hit_tokens: Option<u32>,
    pub prompt_cache_miss_tokens: Option<u32>,
}

Fields

prompt_tokens: u32

completion_tokens: u32

total_tokens: u32

prompt_cache_hit_tokens: Option<u32>

Prompt tokens served from DeepSeek’s context cache. Charged at the cache-hit input rate (typically ~25% of cache-miss). Returned by the API in the usage object; absent for models/responses that don’t report cache stats.

prompt_cache_miss_tokens: Option<u32>

Prompt tokens that missed the context cache. Charged at the full input rate. prompt_cache_hit_tokens + prompt_cache_miss_tokens should equal prompt_tokens when both are reported.
