Struct TokenUsage 

pub struct TokenUsage {
    pub prompt: u64,
    pub completion: u64,
}

Model token accounting for one call or a running total (book T15 metering). L7 providers report it, L9 systems accumulate it, the app/UI layer reads it — one vocabulary across layers, so a usage meter never re-derives units per provider.

Fields

prompt: u64

completion: u64
