Various kinds of errors that can occur in a milter.

Variants

SocketConfig

The socket specification provided to the milter could not be used.

TimeoutConfig

The timeout configuration parameter of Milter could not be used.

SocketBacklogConfig

The socket backlog configuration parameter of Milter could not be used.

MilterRegistration

Registration of the milter’s configuration with the milter library failed.

MainFailureStatus

The milter library’s main event loop exited with a failure status.

CallbackPanic

The milter library’s main event loop exited due to a panic in a callback.

TypeConversion

Type conversion at the FFI boundary (Rust/C) failed.

FailureStatus

A milter library function returned the failure status code.

DataAccess

Erroneous access of context data, such as violation of dynamic borrowing rules.

Io

An I/O error occurred (provided for convenience).

Other

An unspecified error occurred (provided for convenience).
