Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Guardrail

pub fn validate(&self, metrics: &ExecutionMetrics) -> Result<(), PeError>

Validate execution metrics against this guardrail.

Returns Ok(()) if the guardrail is satisfied, or Err(PeError::GuardrailViolation) with details.

Content-analysis guardrails (MustCiteSources, NoCodeExecution) are deferred to Plan 014 — they return Ok(()) for now.
