ignoreFailures :: FailureStrategy Source #

Do nothing, ignore all failures.

writeToCategory :: (FailureReason -> Bool) -> WithConnection -> Category -> FailureStrategy Source #

Write a failure to a category. Use shouldKeep to filter out message failures you don't want to log.

writeUnknownFailuresToCategory :: WithConnection -> Category -> FailureStrategy Source #

Only write UnknownFailures to a category.

writeAllToCategory :: WithConnection -> Category -> FailureStrategy Source #

Write either UnknownFailures or HandleFailures to a category.
