Struct TokenUsage 

pub struct TokenUsage {
    pub input_tokens: u64,
    pub output_tokens: u64,
}

Tokens a provider reported for one call.

Measured, never inferred: this type is only ever built from numbers a provider printed. Where a provider says nothing, the caller estimates and says which it is doing — see crate::graph::types::IngestionReport.

Fields

input_tokens: u64

Prompt tokens, as the provider counted them.

output_tokens: u64

Completion tokens, as the provider counted them.

Implementations

impl TokenUsage

pub fn from_counts( input_tokens: Option<u64>, output_tokens: Option<u64>, ) -> Option<Self>

Usage from a pair of counts, or None when neither was reported.

A provider that reports one side and not the other still measured something, and half a real number beats a whole invented one.

pub fn total(self) -> u64

Total tokens billed for the call.
