Struct UsageRecord 

pub struct UsageRecord {
    pub input: u64,
    pub output: u64,
    pub cache_read: u64,
    pub cache_write: u64,
    pub cache_write_5m: Option<u64>,
    pub cache_write_1h: Option<u64>,
    pub hit_pct: f64,
}

Token usage for one API call, including the cache-creation TTL breakdown.

Fields

input: u64

output: u64

cache_read: u64

cache_write: u64

cache_write_5m: Option<u64>

Cache writes with 5-minute TTL (from usage.cache_creation.ephemeral_5m_input_tokens).

cache_write_1h: Option<u64>

Cache writes with 1-hour TTL (from usage.cache_creation.ephemeral_1h_input_tokens).

hit_pct: f64

Cache hit percentage: cache_read / (input + cache_read + cache_write) * 100.
