Struct TokenUsage 

pub struct TokenUsage {
    pub input_tokens: u32,
    pub output_tokens: u32,
    pub total_tokens: u32,
    pub cached_tokens: Option<u32>,
}

Token usage for LLM nodes

Fields

input_tokens: u32

Input/prompt tokens

output_tokens: u32

Output/completion tokens

total_tokens: u32

Total tokens (input + output)

cached_tokens: Option<u32>

Cached tokens (if applicable)

Implementations

impl TokenUsage

pub fn new(input_tokens: u32, output_tokens: u32) -> Self

Create new token usage record

pub fn estimate_cost( &self, input_price_per_1k: f64, output_price_per_1k: f64, ) -> f64

Estimate cost based on provider pricing

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 Default for TokenUsage

fn default() -> TokenUsage

Returns the “default value” for a type.

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.
