Struct Metrics 

pub struct Metrics {
    pub prompt_tokens: Option<u64>,
    pub completion_tokens: Option<u64>,
    pub cached_tokens: Option<u64>,
    pub cost_usd: Option<f64>,
    pub logprobs: Option<Vec<f64>>,
    pub completion_token_ids: Option<Vec<u64>>,
    pub prompt_token_ids: Option<Vec<u64>>,
    pub extra: Option<Value>,
}

Per-step LLM metrics. cached_tokens preservation is the Module H replayable-KV-checkpoint requirement (success criterion R17/R28).

Fields

prompt_tokens: Option<u64>

Prompt tokens.

completion_tokens: Option<u64>

Completion tokens.

cached_tokens: Option<u64>

Provider-cached prompt tokens.

cost_usd: Option<f64>

Cost in USD.

logprobs: Option<Vec<f64>>

Per-token logprobs (optional).

completion_token_ids: Option<Vec<u64>>

Completion token ids (v1.3, RL training).

prompt_token_ids: Option<Vec<u64>>

Prompt token ids (v1.4).

extra: Option<Value>

Additional operational metrics.

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Metrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metrics

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

Formats the value using the given formatter.

impl Default for Metrics

fn default() -> Metrics

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metrics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Metrics

fn eq(&self, other: &Metrics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Metrics

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
