Expand description
The ultimate “cause” of a failed message.
Variants§
Syscall
The original cause was a syscall error.
Fields
§
error: ErrorNumber
The exact syscall error.
Fatal
The original cause was a fatal error.
Fields
§
backtrace: String
The backtrace, captured if the relevant environment variables are enabled.
