Struct Usage 

pub struct Usage {
    pub input: u64,
    pub output: u64,
    pub cache_read: u64,
    pub cache_write: u64,
    pub total: u64,
    pub extra: HashMap<String, u64>,
}

Token usage counters for an LLM response.

Fields

input: u64

output: u64

cache_read: u64

cache_write: u64

total: u64

extra: HashMap<String, u64>

Provider-specific extra metrics (reasoning tokens, search tokens, etc.).

Implementations

impl Usage

pub fn merge(&mut self, other: &Self)

Merge another Usage into this one by summing all fields.

Trait Implementations

impl Add for Usage

type Output = Usage

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AddAssign for Usage

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Clone for Usage

fn clone(&self) -> Usage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Usage

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

Formats the value using the given formatter.

impl Default for Usage

fn default() -> Usage

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Usage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Usage

fn eq(&self, other: &Usage) -> 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 Usage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Usage
