Struct LlmUsage 

pub struct LlmUsage {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cost_usd: Option<f64>,
}

Token usage reported by a backend for one call. cost_usd is None when the backend doesn’t report a price (most APIs report tokens, not dollars; claude -p reports total_cost_usd, which is 0 under a subscription).

Fields

input_tokens: u64

output_tokens: u64

cost_usd: Option<f64>

Implementations

impl LlmUsage

pub fn total_tokens(&self) -> u64

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

Accumulate another call’s usage into this one.

Trait Implementations

impl Clone for LlmUsage

fn clone(&self) -> LlmUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LlmUsage

impl Debug for LlmUsage

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

Formats the value using the given formatter.

impl Default for LlmUsage

fn default() -> LlmUsage

Returns the “default value” for a type.

impl PartialEq for LlmUsage

fn eq(&self, other: &LlmUsage) -> 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.
