Struct Usage 

#[non_exhaustive]
pub struct Usage {
    pub prompt_tokens: u64,
    pub completion_tokens: u64,
    pub total_tokens: u64,
    pub prompt_tokens_details: Option<Value>,
    pub completion_tokens_details: Option<Value>,
}

Token usage statistics, from completion_usage.py.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

prompt_tokens: u64

completion_tokens: u64

total_tokens: u64

prompt_tokens_details: Option<Value>

Provider-specific breakdown (cached tokens, audio tokens, …).

completion_tokens_details: Option<Value>

Provider-specific breakdown (reasoning tokens, …).
