Name

+

Description

{gun_error, ConnPid, StreamRef, Reason}
+{gun_error, ConnPid, Reason}
+

+

Stream or connection-wide error.

+

These messages inform the relevant process that an error occurred. A reference is given when the error pertains to a specific stream. Connection-wide errors do not imply that the connection is no longer usable, they are used for all errors that are not specific to a stream.

+

Elements

+
ConnPid
+

The pid of the Gun connection process.

+
+
StreamRef
+

Identifier of the stream that resulted in an error.

+
+
Reason
+

The reason for the error.

+

It is present for debugging purposes only. You should not rely on this value to perform operations programmatically.
