Struct UsageStats 

pub struct UsageStats {
    pub input_tokens: u64,
    pub output_tokens: u64,
    pub total_input: u64,
    pub total_output: u64,
    pub last_latency_ms: u64,
}

Token usage and timing accumulated across the session.

Fields

input_tokens: u64

Most recent per-turn input tokens.

output_tokens: u64

Most recent per-turn output tokens.

total_input: u64

Cumulative input tokens across all turns.

total_output: u64

Cumulative output tokens across all turns.

last_latency_ms: u64

Most recent LLM round-trip latency, in milliseconds.

Implementations

impl UsageStats

pub fn record(&mut self, input_tokens: u64, output_tokens: u64)

Fold a Usage event into the stats. Treats incoming numbers as per-turn deltas and accumulates them into the running totals.

Trait Implementations

impl Clone for UsageStats

fn clone(&self) -> UsageStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsageStats

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

Formats the value using the given formatter.

impl Default for UsageStats

fn default() -> UsageStats

Returns the “default value” for a type.

impl Eq for UsageStats

impl PartialEq for UsageStats

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