Struct OpenAiUsage 

pub struct OpenAiUsage {
    pub prompt_tokens: u32,
    pub completion_tokens: u32,
    pub total_tokens: u32,
    pub completion_tokens_details: Option<CompletionTokensDetails>,
    pub prompt_cache_hit_tokens: Option<u32>,
    pub prompt_cache_miss_tokens: Option<u32>,
}

OpenAI wire-format usage. Field semantics follow OpenAI/DeepSeek-openai convention: prompt_tokens is the total prompt including cache, prompt_cache_hit_tokens is a subset. Convert to canonical Usage for any internal billing or metering use.

completion_tokens: u32
