Resolves workflow retry configuration into concrete runtime decisions.
This module turns declarative workflow retry definitions into explicit retry outcomes that runtime step execution can consume without needing to re-interpret the workflow contract on every failure.
Summary
Functions
Returns the configured retry backoff policy for a workflow step.
Returns the configured backoff delay in milliseconds for the next retry attempt after the given failed attempt number.
Returns the configured maximum attempt count for a workflow step.
Resolves the retry outcome after a failed attempt for the given workflow step.
Types
@type delay_ms() :: non_neg_integer()
