Struct LimitTracker 

pub struct LimitTracker { /* private fields */ }

Runtime tracker for agent execution limits.

Accumulates resource consumption and checks against configured limits. Used by RigAgentLoop to enforce cost control and enable partial completion.

Implementations

impl LimitTracker

pub fn new(config: LimitsConfig) -> Self

Create a new tracker with the given configuration.

pub fn unlimited() -> Self

Create a tracker with no limits (unlimited execution).

pub fn add_turn(&mut self)

Increment turn counter.

pub fn add_tokens(&mut self, input: u64, output: u64)

Add tokens from a turn.

pub fn add_cost(&mut self, cost: f64)

Add cost from a turn.

pub fn record_turn(&mut self, input_tokens: u64, output_tokens: u64, cost: f64)

Record a complete turn with all metrics.

pub fn turns(&self) -> u32

Get current turn count.

pub fn total_tokens(&self) -> u64

Get total tokens (input + output).

pub fn input_tokens(&self) -> u64

Get input tokens.

pub fn output_tokens(&self) -> u64

Get output tokens.

pub fn cost_usd(&self) -> f64

Get accumulated cost in USD.

pub fn duration_secs(&self) -> u64

Get elapsed duration in seconds.

pub fn config(&self) -> &LimitsConfig

Get the configuration.

pub fn check_limits(&self) -> Option<LimitStatus>

Check all limits and return the first exceeded limit, if any.

Returns Some(LimitStatus) if a limit is exceeded, None otherwise.

pub fn check_turns(&self) -> Option<LimitStatus>

Check turns limit.

pub fn check_tokens(&self) -> Option<LimitStatus>

Check tokens limit.

pub fn check_cost(&self) -> Option<LimitStatus>

Check cost limit.

pub fn check_duration(&self) -> Option<LimitStatus>

Check duration limit.

pub fn all_statuses(&self) -> Vec<LimitStatus>

Get status for all configured limits.

pub fn progress(&self) -> f64

Calculate progress as a percentage (0.0 - 1.0).

Returns the maximum progress across all configured limits. If no limits are configured, returns 0.0.

pub fn any_exceeded(&self) -> bool

Check if any limit has been exceeded.

pub fn approaching_limit(&self) -> bool

Check if we’re approaching a limit (>80% usage).

pub fn reset(&mut self)

Reset all counters (keeps configuration).

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

Performs copy-assignment from source.

impl Debug for LimitTracker

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

Formats the value using the given formatter.

impl Default for LimitTracker

fn default() -> Self
