    pub output_tokens: u64,
    pub reasoning_tokens: u64,
    pub cached_input_tokens: u64,
    pub cache_write_input_tokens: u64,
}

Accumulated token counts across all events seen by a UsageReporter.

Fields

input_tokens: u64

output_tokens: u64

Total output (completion) tokens produced.

reasoning_tokens: u64

Total reasoning tokens used (model-dependent).

cached_input_tokens: u64

Total input tokens served from the provider’s cache.

cache_write_input_tokens: u64

Total input tokens written into the provider’s cache.

Trait Implementations

impl Clone for UsageTotals

fn clone(&self) -> UsageTotals

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UsageTotals

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UsageTotals

fn default() -> UsageTotals

Returns the “default value” for a type.

impl PartialEq for UsageTotals

fn eq(&self, other: &UsageTotals) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
