Token usage counts for a request/response.

Supports element-wise addition to accumulate usage across streamed updates.

Fields

output_token_count: Option<u64>

total_token_count: Option<u64>

cache_creation_input_token_count: Option<u64>

The number of input tokens written to a provider-managed cache.

cache_read_input_token_count: Option<u64>

The number of input tokens served from a provider-managed cache.

Implementations

impl UsageDetails

pub fn new() -> UsageDetails

pub fn add_assign(&mut self, other: &UsageDetails)
