(UnexpectedDecodeErr f, Applicative f) => Decode f "my-sign" "my-sign" c Text Source #	Decoding allows effectful `f` to allow for troubleshooting and unsafe payload changes. Implementation simply uses `implDecodingF` combinator on the `asUnexpected` composed with decoding function. `UnexpectedDecodeErr` has Identity instance allowing for decoding that assumes errors are not possible. For debugging purposes or when unsafe changes to "my-sign" `Error UnexpectedDecodeEx` instance can be used.
