Struct ResponsesUsage 

pub struct ResponsesUsage {
    pub input_tokens: u64,
    pub input_tokens_details: Option<InputTokensDetails>,
    pub output_tokens: u64,
    pub output_tokens_details: Option<OutputTokensDetails>,
    pub total_tokens: u64,
}

Token usage. Token usage from the OpenAI Responses API generally shows the input tokens and output tokens (both with more in-depth details) as well as a total tokens field.

Fields

input_tokens: u64

Input tokens

input_tokens_details: Option<InputTokensDetails>

In-depth detail on input tokens (cached tokens)

output_tokens: u64

Output tokens

output_tokens_details: Option<OutputTokensDetails>

In-depth detail on output tokens (reasoning tokens)

total_tokens: u64

Total tokens used (for a given prompt)

Trait Implementations

impl Add for ResponsesUsage

type Output = ResponsesUsage

The resulting type after applying the + operator.

fn add(self, rhs: ResponsesUsage) -> <ResponsesUsage as Add>::Output

Performs the + operation.

impl Clone for ResponsesUsage

fn clone(&self) -> ResponsesUsage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResponsesUsage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResponsesUsage

fn deserialize<__D>( __deserializer: __D, ) -> Result<ResponsesUsage, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl GetTokenUsage for ResponsesUsage

fn token_usage(&self) -> Usage

Returns token usage for this response. Zero-valued usage is Usage’s documented sentinel for missing provider usage metrics; response types that carry no usage return Usage::new.

impl Serialize for ResponsesUsage

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
