Struct Usage 

pub struct Usage {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub cache_read_tokens: Option<u64>,
    pub cache_write_tokens: Option<u64>,
    pub cache_write_1h_tokens: Option<u64>,
}

Fields

input_tokens: u64

output_tokens: u64

cache_read_tokens: Option<u64>

Input tokens served from a provider-side prompt cache.

cache_write_tokens: Option<u64>

Input tokens written into a provider-side prompt cache. Billed at a premium over an ordinary input token, so a harness that cannot see this under-reports cost on exactly the calls that populate the cache.

cache_write_1h_tokens: Option<u64>

The subset of cache_write_tokens written at a longer-lived TTL, when the provider reports the split. Absent means “all at the default TTL”.
