Macro fatal 

macro_rules! fatal {
    ($module:expr, $($arg:tt)+) => { ... };
}

Emits a fatal log entry through the global logging service.

Use this level for critical failures that indicate the server may be in an unrecoverable state: the vault directory is missing at startup, a background task has panicked, or a grace period has timed out. A Fatal entry does not automatically terminate the process; the caller is responsible for deciding whether to initiate shutdown.

This macro is a complete no-op if the logger has not been initialized. See info! for parameter documentation and general behaviour.

Usage

fatal!(Module::Server, "grace period timed out, forcefully terminating: {}", e);
