Implementations

impl TokenUsage

pub fn new(prompt_tokens: usize, completion_tokens: usize) -> Self

Create new token usage

pub fn empty() -> Self

Create empty token usage

pub fn with_cached_tokens(self, cached_tokens: usize) -> Self

Add cached tokens

pub fn with_image_tokens(self, image_tokens: usize) -> Self

Add image tokens

pub fn add(&mut self, other: &TokenUsage)

Add to existing usage

pub fn estimate_cost( &self, input_cost_per_1k: f64, output_cost_per_1k: f64, ) -> f64

Calculate cost estimate (in USD)

Trait Implementations

impl Clone for TokenUsage

fn clone(&self) -> TokenUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenUsage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TokenUsage

fn eq(&self, other: &TokenUsage) -> 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 TokenUsage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
