Struct TokenUsage 

pub struct TokenUsage {
    pub prompt_tokens: u32,
    pub completion_tokens: u32,
    pub total_tokens: u32,
    pub cached_tokens: Option<i64>,
}

Token usage statistics from an LLM generation call

Fields

prompt_tokens: u32

Number of tokens in the prompt/input

completion_tokens: u32

Number of tokens in the completion/output

total_tokens: u32

Total tokens used (prompt + completion)

cached_tokens: Option<i64>

Tokens served from the provider-side prompt cache, when the provider reports cache hits (None when unknown or not reported). Always 0 or more; cache hits are a subset of prompt_tokens.
