Structured reason a HaltDecision::Halt was returned.

Deliberately structured rather than a bare string for the built-in guards — this is what lets telemetry emit a machine-readable event that the benchmark harness can aggregate without string parsing.

Variants

FastGuard

Fields

window: Vec<f64>

threshold: f64

SlowGuard

Fields

mean_ratio: f64

window_size: usize

threshold: f64

RevertBurst

Revert burst: k_rev consecutive transactions reverted on-chain.

Fields

consecutive_reverts: usize

limit: usize

RevertGasBudgetExceeded

Revert gas burn: cumulative gas cost on reverts in window exceeded budget.

Fields

gas_cost_burned: u128

budget_limit: u128

window: usize

VolumeWeightedDrift

Capital-weighted drift: volume-weighted ratio fell below threshold.

Fields

weighted_ratio: f64

threshold: f64

window: usize

NetDrawdownExceeded

Absolute drawdown: cumulative net slippage (predicted - realized) exceeded cap.

Fields

net_slippage_loss: i128

max_drawdown_limit: i128

window: usize

Custom(String)

For non-default HaltPolicy implementations. Implementers of a reusable custom policy are encouraged to define their own structured variant instead of relying on this indefinitely.
