Struct TokenUsage 

pub struct TokenUsage {
    pub prompt_tokens: usize,
    pub completion_tokens: usize,
    pub total_tokens: usize,
    pub cached_input_tokens: usize,
    pub cache_creation_input_tokens: usize,
    pub reasoning_output_tokens: usize,
    pub source: TokenUsageSource,
}

Token usage statistics normalized across providers.

prompt_tokens, completion_tokens, and total_tokens preserve the old public surface. Extra fields keep cache/reasoning detail so UI can stop flattening unlike provider concepts into one number.

Fields

prompt_tokens: usize

completion_tokens: usize

total_tokens: usize

cached_input_tokens: usize

cache_creation_input_tokens: usize

reasoning_output_tokens: usize

source: TokenUsageSource

Trait Implementations

impl Clone for TokenUsage

fn clone(&self) -> TokenUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenUsage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenUsage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TokenUsage

fn eq(&self, other: &TokenUsage) -> 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.

impl Serialize for TokenUsage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
