One sampled error specimen from an execution wrapper.

Fields

op_name: &'a str

Op template name the error occurred under.

cycle: u64

Cycle whose attempt produced the error.

attempt_no: u32

1-based attempt number that failed.

tries_budget: u32

The op’s total-attempts budget.

error_class: &'a str

Adapter error class (error_name).

message: &'a str

Full adapter error message.

will_retry: bool

True when the failed attempt will be retried (the class of error that is otherwise invisible outside counters).

squelched_since_last: u64

Admissions squelched by the frequency ceiling since the last emitted exemplar — carried on this line so the squelch is visible, never silent.
