Struct UsageBreakdown 

pub struct UsageBreakdown {
    pub input_tokens: Option<u64>,
    pub output_tokens: Option<u64>,
    pub cache_read_tokens: Option<u64>,
    pub cache_creation_tokens: Option<u64>,
}

Per-dimension token breakdown reported by providers that distinguish regular input, output, prompt-cache reads, and prompt-cache creations (e.g. Anthropic). All fields are optional — providers that do not report a breakdown should pass UsageBreakdown::default().

Fields

input_tokens: Option<u64>

output_tokens: Option<u64>

cache_read_tokens: Option<u64>

cache_creation_tokens: Option<u64>
