_MatchServiceError :: AsError a => Service -> ErrorCode -> Getting (First ServiceError) a ServiceError

Provides a generalised prism for catching a specific service error identified by the opaque service abbreviation and error code.

This can be used if the generated error prisms provided by Network.AWS.ServiceName.Types do not cover all the thrown error codes. For example to define a new error prism:

{-# LANGUAGE OverloadedStrings #-}

import Network.AWS.S3 (ServiceError, s3)

_NoSuchBucketPolicy :: AsError a => Getting (First ServiceError) a ServiceError
_NoSuchBucketPolicy = _MatchServiceError s3 "NoSuchBucketPolicy"

With example usage being:

>>> import Control.Exception.Lens (trying)
>>> :t trying _NoSuchBucketPolicy
MonadCatch m => m a -> m (Either ServiceError a)
