Struct UsedTokens 

Source 
pub struct UsedTokens {
    pub input_tokens: f64,
    pub input_cached_tokens: f64,

Expand description

Amount of used tokens for a model call.

Fields§

§input_tokens: f64

Total amount of input tokens used.

§input_cached_tokens: f64

Amount of cached tokens used.

This is a subset of Self::input_tokens.

§input_cache_write_tokens: f64

Amount of cache write tokens used.

This is a subset of Self::input_tokens.

§output_tokens: f64

Total amount of output tokens.

§output_reasoning_tokens: f64

Total amount of reasoning tokens.

This is a subset of Self::output_tokens.

Implementations§

Source§

impl UsedTokens

Source

pub fn from_span_data(data: &SpanData) -> Self

Extracts UsedTokens from SpanData attributes.

Source

pub fn has_usage(&self) -> bool

Returns true if any tokens were used.

Source

pub fn raw_input_tokens(&self) -> f64

Calculates the total amount of input tokens billed at the standard rate.

Both Self::input_cached_tokens and Self::input_cache_write_tokens are subsets of Self::input_tokens and are billed separately at their own (cached / cache-write) rates, so both are subtracted here to avoid charging them twice.

Source

pub fn raw_output_tokens(&self) -> f64

Calculates the total amount of raw, non-reasoning output tokens.

Subtracts reasoning tokens from the total token count.
