Struct SessionMetrics 

pub struct SessionMetrics { /* private fields */ }

Accumulated metrics for an agent session, updated internally by the runtime.

All counters are monotonic across all turns. Clone is cheap — the struct wraps Arcs so snapshots share the same underlying counters.

Implementations

impl SessionMetrics

pub fn total_input_tokens(&self) -> usize

pub fn total_prompt_cache_hit_tokens(&self) -> usize

Total prompt tokens served from cache across all turns.

pub fn total_prompt_cache_miss_tokens(&self) -> usize

Total prompt tokens not served from cache across all turns.

pub fn total_tool_calls(&self) -> usize

Total number of tool calls executed.

pub fn total_tool_errors(&self) -> usize
